Ok then,...I consider my self bitch slapped.In a street car at 6-800 hp I have seen them last seasons at a time . It’s all in the tune like anything else . Starting with 6 bolt mains put you way head of the game with keeping things in place .
Believe me I know what happens in anything Max effort but these things are pretty damn durable . Price is whatever because I see prices all over . Take a ls7 for instance . Headers , ported stock heads , rpm b4 cam , msd Mamo ported intake . Makes 671 / 577 NA on pump gas . They usually average 620-650 with that stuff . How can you beat that NA from a stock bottom end
Granted this isn’t an ls7 but my point is they are killer engines .
Ls3 heads flow over 300 on the intake side at .600 lift for comparison . My TEA 20511r Cnc heads flow 321 at the same lift . Case in point they are impressive for what they are .
hell if I was doing it again I’d build a 5 or 6 speed setup with a 408 or 416 LS 11:1 on pump gas . It would make over 600 at the tire . Then hit it with 150-200 for the track or some heavy street runs .
My buddy has a stock alum block 416 with mast heads . Cam , carb car . Runs on pump has . 79 slant back heavy cutlass . His dad at 70 years old has been a lazy 9.98 on 125 shot in its setup to take 300 . The car can drive anywhere . It’s just all about what you want to do .
