New to the LT1 world. SUp guys? Just picked up a 79 malibu and it has a 350 in it currently line. Runs fine and all but im a big fan of the lt1 and ive already built a ls1. I just bought a lt1 from my buddy with 50k miles on it. For now i plan on doing cc306 cams with other misc mods, like beehive brings and such. Then some longtubes, a custom off road x pipe and borla stinger dumps.
Later on im going to do the FAST XFI system along with some Advanced induction 200cc heads. My goal is for 500rwhp n/A. i saw on youtube that a guy is hitting 8000rpm with his lt1. how is that possible.
ill start posting build pics as a good since i plan on starting to work on the car saturday.

Yeah I think that guy your talking about might be Alek's Red 355 LT1. 8000rpm is my ideal build as-well. And to get 500rwhp might require a cam a little bigger then the cc306.

If your goal is 500whp then the last place you should be looking is anything off-the-shelf from Comp Cams.
The route I would take would be Advanced Induction's ported Trick Flow heads, an aggressive solid roller valvetrain with a custom-grind from AI along with some sort of aftermarket PCM, such as Fast XFI or 24X. They are arguably the best when it comes to no holds barred high HP LT1 setups.
Don't expect to reach those lofty goals with a hydraulic roller and a stock PCM.
Also, plan on a HUGE budget. Whatever you invest into the motor will have to be equally spent in the rest of the car (fuel system, transmission, drivetrain, suspension, safety, etc.).

Theres a few guys turning 8000 RPM on these motors, but like was already said, the stock PCM cant go past 7000. Check out the videos posted in this thread by quik95LT1 of his car.

He wont give up his horsepower numbers though, but we all suspect well north of 500rwhp.

Ported stock castings and factory PCM cars are getting 500 rwhp (not with your "average" build competence, mind you
).Mike has a lot more headflow, a lot more cam, and revs to...what, 8200-8400? And I'd also say he's above your "average build competence" ..lol! He should be well over 550 rwhp, I'd say closer to 600.

i got nothing to hide lol......i rolled 550rwhp through 29" slicks a dana s60 with 4.56's and a 4l60e.....my 4800 stall vigilante converter was slipping over 11% at 7k+rpm so i suspect that 550rwhp is a modest number....this trans is coming out this winter im having some issues with it so we will see better numbers next year i suspect with a converter that will slip 5% rather than the insane 11%......regardless DO NOT get hung up on dyno numbers they mean absolutly nothing.....
I would certainly hope so!

yes its got well over 300cfm of head flow but the cam isn't TOO crazy considering the grinds out there today......im crossing the line at 8000-8100 right now seems to be quite happy at that point.......and yes if i had a 6 speed in the car with drag radials on it id suspect in the 600 area would be accurate....i figure the motor for right around 700 at the crankand like said above dont out build your budget....its very easy for things to spiral out of control the more agressive you want to get.......ask me how i know

For the rear end I have a ford 9". Suspension I have 2" lowering spindles in front, 1" lowering spring, and for rear I have 3" lowering springs. I have qa1 shocks and struts. Tubular A arms, sway bar, upper and lower control arm. My dad is giving me his 4 spd out of his 700hp chevelle so ik that will hold, only question is if it will bolt to the lt1
