What to upgrade before Swap??
I have a 91 Formula TPI 5 Speed with 305...
JetHot Coated Hooker Headers & Y pipe, exhaust, etc...
Accel Base, Runners, Ported Plenum, coolant bypass, air foil, MSD Digital Ignition System, etc....
My 305 is very fun to drive... @ somepoint, I'm going to replace it with a 383 crate engine & transfer all those parts...
My question... Should I spend money on a new cam / rocker arms, etc... for my 305?
Questions 2. I have the stock heads, will a set of heads used for a 350/383 work on 305?
I don't mind spending money on stuff I can use and transfer later, but I would rather not spend money on things just for the 305...
Thanks for your replies,
Rafael

I'd say leave the 305 as it is and concentrate on building the 383.
