SBF Guys: Tips on 302 performance?

There. Fixed that for you.

 

GT40 heads are in the Explorer SUV's with 302 and 4x4 option. You may find them in a boneyard.

 

From what I can see, the early heads with dish pistons increases C/R from 8.0 to 8.3. With flat tops it goes to 9.9 a little high for today's gas.

 

It all depends on what dynamic c/r you get. Static c/r dont tell you
much the wilder the cam the lower the dynamic c/r gets
you need atleast that if you want the engine to
be near a roadracing engine
Back in the dark ages when you couldent buy any
fsb heads i used 65 289 heads with 1.90/1.60 milodon
superflo valves, ported, screw in studs, polished cc ed chambers,
milled 1 mm, new guides.( Can you do it yoursef or have to farm it out?
