“If your here watching this video your probably not out panic shopping” 😅 because this is basically the 500 hp ls engine combos video 😂 love the videos Richard
I'd love to see a video just like this but mentioning numbers for rough costs. Also, would be great to see a turbo option and what to expect to pay. Thanks so much and im really learning a lot from your videos!
This is good stuff! Man, 20 years ago it was almost impossible to get 500hp on pump out of a 5.7L let alone a 5.3L. People pooped at the ls6 with a "Hot Cam" when it debuted. I really love that 3rd combo. It just makes sense for the little guy, plus a little spray for S&G's.🤘🏻🇺🇸
@@jonwaterbury3312 the first combo looks appealing. The least aggressive cam of the 3 may result in the best streetability among them. The last one already uses a "stage 4" cam, which i assume has worse low rpm performance than lower stage cams of the same model.
The 706 heads should not be dismissed . They scavenge gasses better than the other factory heads even though they flow less . A good port and polish goes a long way with these . Changing rocker arms for rockers with better ratios also helps these heads .
Yeah I’d kinda like to see how much you could get out of a 5.3 with flycut pistons. It’s still stock bottom end parts… no different than adding ring gap right? 🤷🏼♂️
@@richardholdener1727 yes but it goes so fast and the words only are there for a brief moment....... just thought you might have a printout of all the items that you could share
I know this is old but I really wished you had over layed all the combos. Edit. Just watched one of the other videos, iirc it was the 5.3ls vs 5.3lt vs 5.3hybird. And he over layed them plus some other 5.3 combos. Spoiler. The 5.3lt with heads and cam is very impressive
I ha e a 2000 z28 w/5.7 Ls. I'd love to see the same type of build using a similar engine, that would still fit under my stock hood. Would be an awesome sleeper. Also using tuned shorty headers.
Yes but what do you get with cam, flat top pistons and stock heads with spring upgrade! Most people that get these engines don't want to spend 2500-3000 for a set of fancy heads!
You can get big power with factory heads. Cams are they key. With a good cam and a spring upgrade, 450 hp is a reasonable goal. I bet Richard has 20 videos on the topic. The FAST intake is huge money, but a Trailblazer SS intake is cheaper and makes great power.
Well remember that this is engine dyno with no accessories running cooler temps no catalytic converters so I would say these combos are 375-390hp wheel combos realistically
Richard I would like to see you do some small Cubic inch engines like 283 Chevy, 289 Ford, 273 mopar. Maybe build them Exactly the same. And 396/402 Chevy. The other guys.
Excellent info clip. I have a 1966 GTO. It has a 67 engine. Was looking at Ls 2,3 or lq4 9 etc. But I'm starting to think 5.3 because there plentiful and a good price. I had an 06 GTO and fell in love with the engine , 6 speed etc. But 64 thru 67 are my Goat of choice. Not badmouthing the others just grew up with. Does the 6 speed stick align with the original 4 speed! Any other tips would be appreciated. Thanks, Craig
Ok I have watched this more than any other video you have done Richard… this is awesome info. Have you done a similar build with a carb and a single plane intake?
Wonder how hard this would be to do myself on my Tahoe 05. I mean hell if I can put a plane together with just a handful of tools and some written instructions I'm sure if I had good written instructions I could do this myself.
@@scotttimpany2845 its going into my wife’s 03 rav4 lol. I’m keeping the 4t65ehd rebuild ot with a shift kit and a better tc. I’m not planning on making more than 500 crank hp. I’ll be really happy with 400crank hp too. To swap in the 4t80 is a bit tricky and there isnt much for aftermarket support for it. I’m thinking about swapping in a built th125c too. Should be a fun sleeper. Cam, springs, headers, intake. Should do just fine.
I've had every motor in every different vehicle GM offers from the late 70s until current at the moment I have an 8.1 l Allison transmission truck with a raylar cam I'm looking to work on but more importantly the daily driver 6.2 l92 Yukon Denali and then looking to do an LS in an sn95 mustang Cobra rolling chassis I got from California
Luv you videos keep up the good work. I needs some help and some experts advice. Was wondering if you could do a video on oil catch can for turbo setup. I'm having issue were I'm having oil blow out of my catch can filter and their is no oil in can. It is a amazon cheap catch can so maybe that's the issue. Was wondering if you should do both valve covers to catch can or do breather and one line to catch can. . I'm hoping I just hooked it up wrong . other issue is it's blowing out milky oil which I'm hoping is just condensation. Just to let u know because this is or is a common mistake the throttle body hose is not hooked up to valve cover.
Richard, perhaps not the video to make this comment, but the adage that there's no replacement for displacement, apparently isn't true (not counting boost). On the 2022 Corvette Z06 they do it with RPM and breathing. My question is could GM have achieved a similar output with displacement and better heads and cam on their LT engine? I know they've already done 7L, and the high deck LSX can get to 7.4L. I know they went this rout for IMSA racing which is restricted to 5.5L. The Z06 will get 670 hp (net ~ 740 gross) at 8600 rpm.
First off I always love your videos sorry I always forget to hit the like button so I've been thinking hard about whether or not to put a cam in my 53 and I've decided that I'm going to but I want to keep my VVT so I'm going to buy the VVT limiter kit from comp cans it's only like 75 bucks but I'm trying to figure out which VVT cam would be best it seems like there's only a few and the ones from Texas speed seem pretty good except they have crazy high lift and I just don't see how that's possible with out piston to valve clearance on a stock bottom end if you maybe want to do a new video maybe try vvt cams and then I could know which ones best
@@richardholdener1727 okay thanks yeah I remember you saying that now that I think about it but I don't want to go that radical I'll look at someone else's thanks
Blather? Like, then subscribe, then "blather" right on outta here then Lol, Richard, if you see this comment, I currently have researched these LS engines for 100s of hours now(your videos). I have a 05 Silverado short bed , single cab, classic I've been restoring/custom building , and im just very torn on what direction to go. I have notes on ALL combos for. 4.8/5.3/6.0 builds, but I am stuck in between wanting a descent N/A build, but also able to put a small turbo on it down the road without any downfalls that can maintain a decent mpg(15-20) when driving far distances(drivability/efficiency) . I like the 4.8 idea, and just adding overkill heads, and a descent "truck style" cam ,high pressure oil pump , etc... But then I worry about not replacing all the bearings/not measuring internals/dirty oil and coolant passageways.... But also like the idea of taking a 5.3 and having it bored over to a 5.7 and keeping it N/A, and going ahead and having a machine shop match a good combo of crank/rods/bearings/ pistons /cam/ head work etc.... while I'm at it ......and never adding a forced induction.. Should I just buy a junkyard 4.8 and have the turbo ? Or would it be a similar cost to build the 5.3 fresh/brand new ? And what would you think the differences in power/longevity /effeciency would be? Lmk,. New to this, but really really love your technical videos that teach what camshafts ACTUALLY. Do, and flowing different heads/combos. Etc. So us newbies can actually understand there is More to a pushrod v8 engine, than just having it make that "loppy" sound at idle. Lol thankyou, hope to hear from you. Peace .
Rich...? Have a idea... since I've been watching seem that trolls have an issue with some of your explanations on stock... Maybe do the factory assembly untouched vs stock short block with optimal clearances. I get it but some Don't understand the rules of performance engines and Max effort.. just an idea. Keep it going great content as always. Merry Christmas and have a great Dyno day... Lol
Might be a stupid question but can you pull a junkyard 5.3 and without taking it to an engine shop bolt on good heads fast intake longtube headers bigger cam and it be a 500+ hp dependable motor?
I bought an 84 Monte Carlo with an 5.3, it has jegs intake manifold, long tube headers, 93mm throttle body, Texas speed stage 2 cam, spectre cold air intake and flow master exhaust and turbo 350 transmission and Terminator x efi. Any idea how much horsepower that would be?
Richard good to see you!!! I haven’t been around much lately due to a schedule change at work so I can’t participate in your live streams. I’m building an iron LS1 5.7 with flat tops, 862 heads with a home port job done by me, for now a stock LM7 truck intake, I believe with the measurements I’ve taken and the gaskets I’ve chosen my compression ratio will be right at 11:1. I’m using the sloppy “best” cam. What are your thoughts on this combo and how much power do you think that would make?
Richard i have a set of 799 heads on my 5.3 and just orderex a complete btr truck norris cam kit how can i get the most hp out of this set up na any tips?
Hey Richard. I know I've brought this up before but I'll bring it up again because some recent events have peaked my curiosity... how interested would you be in testing a crossfire setup? And for that matter, what would you need to do it?
@@richardholdener1727 Well, I have a totally stock intake (2 actually), lid, and throttle bodies I could send down for testing as well as renegade and one that I am working on porting and modifying with a friend on a flow bench. If it does interest you I'd be more than happy to send something your way for testing in the name of science.
Does anyone know what kind of vacuum the 5.3 with a summit stage 4 will make at idle and cruise? Just curious if I'm going to have any issues with power brakes or anything. It's a manual car so no torque converter to fight with
@@richardholdener1727 Stock 4.8 with ring gap. Stock truck intake "Truck Norris" camshaft, stock truck manifolds. Twin holset hy35w turbos. Using internal waste gates . Has "rising boost curve" boost creep over 4000 rpm due to gates not flowing enough. Going to port them. So far Works good for me 👍.
Has anyone ever built an LS the OPPOSITE way - as in, making all torque with not so high-revving HP? I miss the old 350/383 for that! I'd love to build the LS in my '07 (GMT-900) Silverado 1500 to yank trailers around much easier than I have been. I hate how I have to scream this thing up to 4-5k just to make any power. Below 3k, it's useless - the exact opposite of what I want in power output! I wouldn't mind at all if the engine signed off at 4k RPM, but rivaled a Duramax in torque numbers down low, if that's even possible.
Put a smaller cam in your engine and you will see bigger gains in hp and torque on the bottom end. I have noticed more bottom end torque when using 3:73 rear end compared to the 3:42.
If it has VVT adjust it so the cam is advanced in the lower rpms and add some spark timing. You tuner should be able to help you with that. Every LMG VVT table I have seen for US stuff does nothing but retard cam timing to reduce pumping losses during cruising.
@@osarmrnot No VVT until 2009 if I'm not mistaken. Mine definitely does not have it. One less thing to break as far as I'm concerned, lol. Everything else on this truck has! I'm at 117k miles, and my oil pressure is dropping off fast. Won't be long before I'll be yanking it for either a rebuild or a crate replacement. Ideally I'd have Texas Speed build what I want, and throw a Whipple on top ... but with my funds, that's not happening. More than likely I'll be rebuilding what I've got out in the shop here with whatever I can find that'll make it torquey.
@@tskraj3190 I already have 3:73. It pulls just fine with the stock LMG, Hypertech canned tune, Corsa cat back, and K&N CAI (minus the K&N filter), but I know it is capable of much more. Smaller cam might be the ticket to shifting the power downward in the range. I'll have to learn what components together can make this happen. It's like starting all over again. Just when I learned everything there was to know about the 350, the LS comes out. Figures!
Budget boost built? Or building a 5.3 for nitrous would be interesting. My family just got a fully intact 5.3 with a 4L80 along with harness and ecu. Thinking it would be nice in a Fbody roller with a 200 shot or turbo setup. The goal is 550-600whp.
I have an issue of Engine Masters magazine from a few years back that features a 5.7 HEMI that made over 500hp with the factory heads that were not touched .
Richard, what 4 point steam vent is used for the lsxrt intake? I currently have the factory 4 point, but I'm getting mixed information if it will work or not.
It should be I went with the A-Team Performance version. If you go that route, get their Aluminized heat sheath to run the hoses through as you install it. That will help protect the manifold from heat soak since the driver side front-to-back goes on the outside of the manifold.
At 14:11 you talk about piston to valve clearance, limiting you to be able to put in a bigger cam. But doesn't the head flow design dictate the cam lift? No sense putting in a bigger cam if the head flow doesn't support that. I would like to see you do bench head flow, and then pick a cam that matches that. Maybe you've already done that.
Hey Richard I have a 5.3l with Ported 706 heads with Bigger valve I'm running a comp cam it the duration is .050 intake is 235 in exhaust is 242 lobe lift Is .3650 intake in exhaust is 2490. Lobe separation is 111.0. I'm running a ls3 intake with ict Adapters. So my Question is am I losing powers by running that intake with the adapters. And would I be better off running a fast 102 intake?
Can you make a stock 5.3 with stock heads making 500 hp n/a. Doing it with a big cam headers intake and big throttle body....you can port and polish and shave the heads or use any stock LS heads...Can it be done???? Anyone please help.
Hello Richard , new to your channel. I have a 2002 gt mustang, 106,114 miles. I would like to get around 500hp . Any help? Thanks. Something like the cobra. I don’t want the 5.0.
I got a LM7 in my 2000 silverado. I was thinking on rebuilding the engine and then throwing boost at it. What would be easier and more durable a crate or do the rebuild. My hp goal is around 600 to the crank.
7:57 if the stock motor made 354 @ 5500 rpm. Adding nitro the engine would have still peaked 5500 rpm. For the engine to at 6500 rpm. You had to change the cam. Installing a high rise intake is not going to raise the peak 1000 rpm.
@@richardholdener1727 so what pushrod length did you use for this combination? 5.3? And i was in the impression that the 5.7 LS1 we're a different size than it's other Beratern LS's
Richard, im putting together a l33. Im looking for 500hp. I was wondering if i needed this much cam for it. It will be sbe, flat tops, tea stg 1 799 heads milled for 10.5-11:1 comp, and a lsxrt intake with 102mm tb. Im looking at either the ss2 or the 227/243 comp cam.
