Roller rockers
Would putting roller rockers on an otherwise stock LT1 valve train have any power increase or do really have to do a cam to get any benefit? Also does going 1.6 ratio have any more benefit?

1.6 roller rockers and LT4 valve springs were one of my first mods. I didn't dyno before and after. But, the car did rev alot smoother, especially above 5000 rpms.
I've heard you will gain 10-15 hp with this mod.

Why would you have to put in lt1 springs? I've heard that the cams are about the same. Are they a higher rate? Why not just use comp. or crane aftermarket springs if you want more rate?
