Thanx 540 love to make my hot rod bud chuckle..my channel is old ridge runner race truck.give it a look if ya want .I haven't had much time to get any more vids up lately..but 1st one up is my new 385 roller..sounds better towards the end
This is without a doubt the most informative series for engine nerds I’ve seen. Do not stop. I’ve read your articles and now am hooked of the channel. Thank you.
Richard is giving away information most tuners and engine builder keep a secret or don’t want to tell you. To me Richard is an awesome dude helping us all make serious car gains 💪
I always enjoy the series you do. This one should be interesting. I think you should do a series on how to get the most low end torque N/A for towing with the 4.8 5.3 and 6.0 with different size headers, cams, intakes, heads. Find a set-up that give the best area under the curve below 5000 rpm or something. And then maybe throw a turbo on the best set up of each just for fun. Keep up the great content!!!
The intakes and heads don't really matter under 4k rpm. There is plenty of air coming through the stock stuff already. The Crane 210 seems to be a good combo that starts taking off about 4500 rpm. Below that, meh, it's a lot of work for not that much gain versus stock. Headers and exhaust are up to you. Keeping it quiet would be a priority for long towing trips since the drone can get really annoying after about 3 hours.
I really like where this series is going. It applies to the average guy with an average paycheck and a friend at the local junkyard. I have a feeling it will show the capabilities and the limits of certain combos. I'll be watching every video!
Thanks for keeping the videos coming, especially with everything that's going on right now. Your info is invaluable for those of us working on an LS swap.
That beginning part of the video would answer a lot of people questions, i appreciate you taking the time to do this and actually explain. I will be sharing your videos with many
Great content. Extremely relevant. Disregard the “too much talk” comments. What you say adds real value to the visuals. Keep the videos coming, please.
I need/want 500+ out of my 6.0 with minimal loss down low, preferably no losses at all, patiently awaiting next vids. Thanks again for the BEST content on LS engines, and all the other engine platforms as well !
Great work Richard! This is kind of information we like to see. I have a feeling a lot of cam companies will be contacting you to dyno their cams, and we cannot wait to see it!
Hi Richard, your videos are great, so much information for free its something grear, keep going like that. In the future i glad to see a 5.3 bored to 5.7 because this is the cheapest way upgrade the ci on this engine, thanks for all you effort to make this videos.
This is one of my favorite videos. I put a camshaft in my 5.3 (205/217 .500 lift) it’s similar to a the crane 210 cam run in this video. So I have an idea of what kind of power I’m making. I also put this same cam in my dad’s 6.0 truck.
I love you and everything you do, but could you test the summit vs comp truck cams on the 5.3 motors? If not I know you’re flooded with requests so don’t worry. Just thought I’d ask since there is almost 0 info and videos about summits truck cam line and how they compare.
Just like the old days , fact power info. Lots of room to unbottle power. One topic I've not seen .. with cam geometry vs displacement . I'm glad you showed the shift with displacement. IE: medium cam in a bid cube = tall cam in a small cube engine. It's all volumetric.
@@richardholdener1727 thanks for the reply! I mean overlay the dyno graphs of each engine when they all made 400hp. With the aftermarket camshafts, just to see the torque and rpm difference between all 3 engines.
Love this channel, so informative. Would like to see the timing curves you use when comparing cams, just to show how each cam affects the dynamic compression across the rev range. Keep up the awesome videos!
Anxious to see about what my 6 liter makes. Bone stock 'razor blade' rebuild, with a Summit stage 3 turbo cam. I've had several people say that my turbo cammed motor won't like nitrous. I believe the complete opposite. Specs are .600/.575, 231/238ish, 116(+5). The cam has 2 degrees of overlap, which would help seal the cylinders and not let boost leak out of the exhaust. The same principles apply for nitrous. While having little overlap will create alot more cylinder pressure, whether with nitrous or turbo, it seals the nitrous from flowing out the exhaust before or instead of combusting it. My plate can go to a 600 shot. Stinger 2 plate. I've read that these crakes and rods are strong. I guess we will see.
I think it would've been interesting to see at the end of the video all of the 400hp combinations compared against each other just to see the different torque curves all next to each other. Otherwise, great video!
LOVE all this ls stuff I really been trying to learn all I can about this engine family and this is by far the best channel I have found keep up the good work Richard..
Richard I would like to see you use the TSP 224R 224/224, .600"/.600", 112 LSA on the 4.8L with headers and 799 heads, ported throttle body and ported truck intake manifold and of course the tune.
@@richardholdener1727 well yeah I haven't seen you use that specific camshaft and it is actually a great camshaft that works well with a stock converter and doesn't affect vacuum. And I'm sure there are a lot of us LS owners who would love to see that in a 4.8L with stock 799 heads and also to see in conjunction with that what the ported throttle body and intake manifold will bring us numbers wise. Haven't seen any dyno numbers on ported stock truck intake and throttle body.
Richard have you Been approached on getting your own show ? Have you thought about that or looked into it maybe ? The level of information that you're giving out is absolutely extraordinary I do honestly believe that you should have your own show not just on RU-vid I mean actual show maybe on MotorTrend or something
man you're giving me ideas... ideas that might make my ford guy brother disown me. ideas involving that ranger i drive back and forth. i've had the idea honestly of engine swapping but you're definitely throwing gas on that fire lol.
I'm pleased to see that the 4.8 didn't lose anything on the low end, it seemed to stay relatively the same. All the gains were up top, as I suspected. Judging by the dyno graph, a cammed 4.8l wouldn't be anymore 'sluggish' with a stock stall, compared to the stock engine configuration? I'm on the fence with the 4.8 in my 11' RCSB silverado, should I work with what I have? or swap a 6.0, or 6.2? Then convert over to a 4l80e? Decisions, decisions.
On your engines do you delete the DOD! I want a v8 in my truck. If you're going to delete you might as well change the cam and lifters for up grade and lifter trays if something is available! Great information! I got a 4.8 and 5.3 I could work with and my tow truck has the 6.0 so yes I find your dyno and cam selection as Graet content I just got to convince my wife I'm fixing to tear down the truck! Lol
Would love to see a comparison of log manifold vs header for headers and manifolds that flow the same on a turbo application. I want to know if the tube length effect falls off when you put it under pressure driving a turbo.
When he said the HP at the wheels is about 100hp less, it’s about as spot on as you can get. The first engine is a 4.8 and it dynoed at 336 with headers. My completely stock 2000 Silverado made 200whp with a stock tune and a little over 220 whp with a safe 89 oct tune (Dynojet, 2nd gear pull, 75F and 50-60% humidity). With headers and 91/93 oct (allowing more timing), it’d likely make 235-240 at the wheels; and likely a few more if the pulls were done in 3rd gear (1:1 ratio) instead of 2nd; which was done since the tires were speed rated for the top of 3rd. Besides, I wasn’t chasing big peak numbers. 2nd gear was good enough to see the gains.
Dude you are a champ!!! Could you please make a video about what you do to the inspect a junkyard motor before you buy it/ things to look for and what to avoid?
I love your videos, but sadly I am going to have to do the opposite of a lot of recommendations to get my 325E's rear diff to live. I bought a 5.3, it appears I should have got a 4.8 and add'd the not so great fabricated intake and stock exhaust......LOL, nothing like have to choke a motor so your car doesn't turn into a hand grenade.......
i wanted to see the last 5.3 cam run in the 6.0 to see what kind of power that made. other than that I love your videos. lots of great info to help with my tuning.
Those numbers on the 5.3 were those with stock Tb and injectors and stock heads just with tune kicking around the idea of a junk yard 6.0 build to throw in my avalanche just want good daily driver with more power stock converter but going to upgrade 4l80e
Its amazing how easily the l.s series motors make serious power compared to the old school sbc and the cam profile can be very aggressive and still have a decent lsa for idle characteristics I guess due to the change in location and being just fatter overall
So are the LSX motors going the way of the SBC? It's been 20 years and all of the power figures and methods have been found. Do you think this next generation of GM motors will continue to the legacy of cheap power GM is known for?
