I love my LT4 powered car but LS was respected from day 1. It was so revolutionary back in 1998. How many cars had more than 325 hp back then? 325 back then is like 700 now if you look at current competition.
Are there higher flow direct injection injectors and pumps or do you revert to port injection for high horsepower? Are the aftermarket (incl Chev) going to be selling high deck height blocks?
Does anyone have any information about the stock GM LT4 bearings? Do they fail at high horsepower, or is that something to do with the factory clearances/balancing?
Hiya fellas I am back after 4 years...still have my 17' SS 6 speed Camaro but now over 70k miles on it and still runs like new and pulling like a freight train.
Hamad Al Shaqsi The LT4 is better for Boost. The LT1 is great but you need the better pistons and the crank that the LT4 has. The Camaro SS has the LT1 the ZL1 has the LT4 with the Supercharger. I have the Camaro SS 2018 would love the ZL1.
Well shit, Ik the intake/exaust layout is diff between the 2 heads. I wish there were more online info on gen 2 lt1's. Thanks for the heads up tho, tbh forgot about this comment.
Hello LME. I love what you guys do and I actually live in Houston Texas. I have a question for you guys. Can you guys make a Camaro SS rev to 7500 RPM like a Mustang GT? I like Camaros but I think they need at least a 7000 RPM redline.
@@toddb3394 I'm late but thank you I've own Gm cars since I was born my 1st was my first car at age 15. A 85 z28 Camaro 305 . 7 more 3-5th gens Camaros including 1 97 firehalk lt4 car ran 11.78 on the old nitto 555 373 gear 230 238 cam car I was in my early 20s. Whipped many stangs. An 1 91 lt1 355 tune port black red int veet drove in high school along with my 1st car eva at age 15 85 z . My fastest to date is my 2000 z28 mistc teal flip flop green color factory t56 6 speed car. Now is the fastest true stock suspension on small tire 28s in my city an all southern tri city areas. Even my 1st upgrade bk then was a Gm performance hot cam with 3000 stall 373 gear car stock t56 stage 3 clutch car with just a cam harden push rods long tubes Gm free Hp mods ls6 intake 243 heads i can remember constant 6,800 - 7000rpm clutch drops an that was my very 1st aka the HULK very 1st street drag combo 4 more combos as cars got faster an faster have to keep my current set up hush hush due to money grudge racing but yea the commite was made don't make since or don't believe me couse anyone knows or call vengeance performance an they will tell you 6800-7200 is actually were they costum grind there small baby cams ls cars even turning 7000 7200 easy so I'm positive the new lt1 revs high but if you do research on Gm push rod motors our motors make peak hp an tq at a little lower rpm an in some cases if you look on the dyno charts after that power is made depending on your cam or motor set up after you reach peak hp anything after that it will fall off an you just adding extra wear to your motor Gm an the over head Ford motors are completely different in how they make hp. But that's the reason why even the die heart Ford guy will do a ls swoop couse ls an Gm motors take more abuse an make more hp at a friendlier budget price.
I would have to say this about these engines . Both times me and my wife owned a Cadillac one was a 2014 and my current one is a 2018 we had lifter problems . The ‘14 would have a lifter that every once in a while would collapse then after a minute would pump back up . Then the ‘18 out of no where dropped a cylinder cause of lifter failing and bent a pushrod . 35,000 miles . That’s in a Cadillac . How can these engines take abuse like they would in a Camaro or a corvette ?
Are you sure it was a failing lifter? I had the exact same thing happen on my 15 Silverado 6.2L, snapped and bent a pushrod. Took it apart, replaced the pushrod, changed the oil, and it’s like nothing even happened. I’m still getting a random misfire code from the fouled plug but this literally turned $1000 of work into me givin my buddy, who’s a certified Chevy mechanic, $100 for his time and effort.
Lifter issues are due to active fuel management and displacement on demand systems in the l86 and l83 engines. LT1 and LT4 engines have differences in the valve train which allows them to handle more abuse.
From what research I have done personally this comes from failure to change oil filters and oil. Oil filters are more important than the oil change on all these new blocks.
The LT4 has a slightly stronger block. Steel crank better rods and forged pistons. And will easily take 1000HP with a well engineered twin turbo setup ....
@@markjmaxwell9819 ig I need to buy the boostline drop in piston and rod setup...hate to spend the $2650... thinking of trading this thing for a 6.0...its just too dam expensive
@@markjmaxwell9819 I'm serious...I'm just going to do a Gen 4 5.3 with stock bottom end(with ring gap) and ARP studs,trickflow heads with BTR springs and head stud kit,BTR stage 3 turbo cam and a nice intake manifold with two cheap ass ebay turbos.... going to start with that and build the 6.2 slowly while running that combo or I may trade it for a Gen 4 6.0 🤷🏾♂️
So ls can handle 1000-1200whp and the lt motors can handle 1500whp ish nice that’s my goal of around 1400-1500whp with a procharger F1X even at biggest for me an F2 procharger
Give me a 327 with a few nice bits inside at over 7k rpm with a carby 11.1 comp a solid cam even flat tappet iron heads or maybe I could slip an ally set on there a nice solid timing chain reworked aftermarket or shed modded sump a manual trans in just about anything that ain't huge And u shall be exposed to a pleasure and the song of a lil giant killer that has been forgotten about unfortunately
@@keith-jo6wg what era was the lt4 you are talking about I'l haftoo have a good look I'm very old school 40 years ago A friend of mine in Australia Had a 327 small journal Built by a fellow that became a good friend talented man He had a bread and butter engine workshop in a small city in New South wales But mark the shop owner liked doing lil specials on the side If things got quiet It took him over a year of his part time to build this lil engine With attention to detail Solid cam flat tappet Can't remember specs Fuelie heads ported and match ported Victor jnr Balanced And squared up Good forged slugs Can't remember rods Guide plates Screw in studs and manly rollers 650 Holley mechanical Top loader and a 9 inch It easily revved to 7 plus It was in a four door Holden hj sedan Dumped on the ground pretty well Not a real light vehicle With firm suspension 235 50 series on front 265 50 series on back I drove this vehicle at 240 kph Ish I was well past the 220 on the clock and his Speedo had been calibrated quite well at time of rego it was one of the conditions by the fella that inspected it and it had a lil more But I ran out of rd And I ran out of nerve I was 19 Go the mouse Scared the Shiite out of me And to hear that lil sucker wind through the gears was something I won't ever forget It smoothed out beautifully at about 6k and was asking for more The whole way At the time 40 years ago the build cost him 5k or so Back then that was a substantial house deposit a block of land was less than 20k Anyway I've always wanted one the sorta the same Yeah I know the past is gone Cheers
Vosovogalsyncope carbon build up is one small problem with the new LT motors but the benefits have a way longer list . Did you see the l83 ( gen V 5.3 ) make 800 hp on #8 of boost ? That’s insane . I don’t really care about your pos , stick with the bow tie.
That's one of the best things I read in years old school has potential that has been written off so many times looking at the differences here shows some of the weakness in the LS the only LS I've ever been impressed with was an LS 7 a friend of mine had greatly engineered engine But will over time still suffer from 4 bolt per cylinder and webbing issues if consistently driven hard An aquantence of mine was putting old school blowers on them for skid cars without upgrading anything Sept lifters and rockers valve train stuff he windowed that many of em it was criminal and he wernt even getting a hell of a lot of power out of em till he got sensible and run em on alcohol with mechanical and kept off the dickhead limiter Some of the toughest cars he was competing against were blown small block chevs and old school blown Ford's with mechanical injection and alcohol I'd say most were after market or special blocks though or had been engineered for reliability They should have different days at skid fests one for cars with limiters and one for cars without and I'l stay home for one
I drove a LT-1 in a 1994 Z-28. I wasn't impressed. I drove a L88 5.7L 350 in a 1980 Stingray Corvette. That car was a piece of junk. I don't like Tuned Port Injection either. I think Chevy in general I just didn't like. My First two cars a 1983,1984 Z-28 5.0L 305. I got a Mitsubishi Galant 2000 now and, I'm happy.
