My Dad and I are restoring 1967 Mustang in memory of my little brother Who always wanted to restore an old car with us.

What im needing help on is the motor, Right now...

302 bored .060 over
Flat top Pistons w/ Valve reliefs
We think Stock crank haven't checked.
B303 Hydraulic Roller Camshaft
Edelbrock AVS Thunder-series 600CFM Carburetor
Edelbrock Intake 1500-6500 RPM Range


Were wondering what heads Would give us the best flow And what size exhaust to run. Many people have been saying either the Trick Flow twisted wedge 170's with 59cc chamber, Or the GT40-P heads off the Explorers

Any help is much appreciated

It sounds like you already have your block but some of the big 69-70 family cars that used the 302 had really beef up bottom ends just like the Chevy 350 4 bolt main motors just to lug those heavy cars around as i have seen one before that i worked out a deal for friend to get it.. he told me it saved him alot of money because of the crank and rods that was used in those enigines .

I was hoping to get some good info on what heads to use.. im not sure which ones would be best

The TW or AFR 165's would be my choice I don't think the GT40's will perform or breathe anywhere near aftermarket heads.

I'd have to go with Jon on this one... the AFR's or TFS would be my choice if you are going for performance.

When i looked at the flow charts it looks like the Twisted wedge have a better flow, unless i didnt read it right.

What size headers and Exhaust should it have with the Twisted wedge heads? to get the best flow
