Installing a cam, have a few questions.
I want more power so I figured I would go with a different cam. The one I found is Crane PowerMax it has 204/214 duration and .423"/.446" lift. I heard that you dont want more than .430 lift so is that going to be to much. I want a cam that is as big or a little bigger than the cam in the 305 manuals and the other cams that ive found are a little smaller. Also will I have to worry about the computer not working right with this cam. THANKS

Personally, I think the cam is too small considering all the trouble you have to go through to replace the cam. The computer shouldn't have a problem. That cam isn't much different than the stock cam that cam in my 305. But since you don't plan on doing the heads that cam should work fine. I am changing my cam and from what I have heard the stock heads will be a big restriction so I plan on doing them at the same time as the cam. I'm using either a 212/218 cam or 218/224 CompCam XE.
