Default Just a thought...

what would happen if i got some 1.8 ratio rockers and put on my car with the mods in my sig? it would make my cam seem like a 231/237 .633/.630 112.
would that be safe with stock 5.7 heads? what benefits/deficits would come from having that much more lift? would if affect the power curve any?

thats only if he doesnt have a match set of springs. there was a good thread on it a while back. he did jus rockers and lost some up to. then he put in the springs that were supposed to go with it and everything was fine in closing, a crane or comp 1.7 rocker is best. im gonna recomend the crane 1.7 ls1 rockers

true but thats the high point for stock rockers, although i think i read that its really 1.69 or somethin like that and start at 1.59 i think. the crane rockers start at like 1.79 then go down to 1.7. do a quick search and itll be clarified for ya

Do you mean there's as much as .10 variance in the ratio of the rockers..production variance?
