iam building a 5.3 and iam trying to find out how big i can go with the cam with out changing my rockers, ill change the springs but everything is stock on this engine, i just want to go bigger on the cam, the guys at comp cams gave me a cam they thought would be good,The cams duration @ .050 is 206/210 Lift is .450/.480 with a 112 LSA, iam not sure what kinda of gain it give over stock, but i would like to get as close to the 400hp mark as possable with out changing to much, this engine is a swap out for my 1990 chev short bed excab 4x4.thanks for looking any referances would be good.

 

LOL wow thats not much of a spec'd cam..

There are guys running well over .600 lift with no rocker problem...

400 crank or wheel hp??

 

I run a 223/230 .610/.605 in my lm7 little to big but o well found out the hard way

 

thats hugh, ya did not have to change out rockers or push rods, or valve springs, then i guess the skys the limits.....

 

thanks for the input, what about valve springs?

 

Cam size dictates valve springs.

 

i cant believe anybody would spec out that cam in the op

 

That cam is barley bigger then stock and the stock ls1 cam is even bigger then that one

 

thats what the guys at comp told me, i thought it kinda small after seeing all these cams out there in the 500 and up lift.

 

thats what comp said i should get, but iam still looking
