I am rebuilding my engine and am buying the whole super stock master engine rebuild kit from PAW. They do not have the stock cam and have to order it which is gonna take like 10 to 15 days. The other option I have is go Powermax roller cam for my 305 TPI. What I am concerned is about my computer, since I have to go with atleast the 2500 - 6000 rpm cam with .509/.528 lift, I am not sure if I should mess with my computer or not. Also I dont know if i need any performance pushrods.

 

You might want to consider a less-radical alternative. The Crane 104224 is their 2032 computer-compatible Powermax roller version that shouldn't make your TPI barf.

I have the 2050 flat-tappet version of their Compu cam (slightly more duration and lift than the roller version), love it.
