    Crane Roller Rockers hp???

    How much horsepower would I get from Crane 1.7 roller rockers? and dont tell me its a waste of money because I already bought them long time ago for $200, and also would I need different pushrods?

    about 10-12. yes you need shorter pushrods for correct geometry. with stock heads and such, you will need 7.250" long pushrods.

    Thats actually pretty good hp, I thought it was going to be like 2-3, you say I need shorter pushrods but what I want to uprade cams, could I still use those shorter pushrods.

    the rockers are fully adjustable. so, yes you can keep the pushrods. i've had the 1.8 vinci/crane rockers on the wife's car. picked up 17 rwhp with the stock cam. changed cams and have the heads cut almost .020" over the years. never had to change the pushrods.
