Hello everyone!
I have a couple questions for you guys. I just bought a 2001 Corvette with a modded LS1 in it. I have plans of taking to dyno tuner when it comes out of hibernation, but thats a long time from now up here in the "frozen tundra". Its just too long of a winter here in Wisconsin.

1. I was wandering if anyone could guesstimate how many horses it is making. Since I bought used and seller did not have reciepts (I know, I know, it was a bad idea)I can only tell you what he has told me.

"Modifications are LS1 ported and polished heads, 216/220 Comp camshaft, Comp roller rocker arms and pushrods, Vortex ram air intake, ported and polished throttle body, 42lb fuel injectors, performance fuel pump, LG longtube headers and X-pipe".

2. A local shop changed out the valve springs because one broke. They recomended getting rid of the high ratio roller rockers and replace with the stockers. They figured mine are 1.8 ratio. Anyone have experience with using these rockers and a high lift cam (valve float)?

Thanks to everyone that chimes in.

I dont think that's a big cam the lift is .525 .532 something else cause the spring to brake probably defected, wrong springs etc but your hp i think is in the 385-415 is it auto or manual??

 

It is a manual. Is that crank hp?

 

no, rwhp!! i will say is in the 400+ because is manual and assuming it has everything he told you

 

low 400s is a ballpark figure
