302 Head Question...

I think there is a solution to the OD/tunnel dilemma that does not involve cutting. IIRC it is a custom cross member that bolts in place and uses a stock isolator. It does require shorter drive shaft and a re-set of the pinion angle of the rear axle.

Don't know what car the wheels are going on. 7" wide with a stock offset fit fine on both of my Darts. The '73 4-door has disk brakes (pushing the wheels out a little farther in front) with 205/60-15s on Magnum 500s. The '72 Demon has a disk brake '75 front end under it with 235/60-15s on cop car wheels. Clearance in the back is a little close, but no rubs since installed 3 yrs ago. In the front, the fenders had to be massage a little to keep the tires off of the top of the wheel well opening in spirited driving.

For what it's worth, I tried 255/60-15s under the Demon. The rear springs would rub the sidewall in quick turns. No problems with the fenderwell. Up front, the tires would bounce off of the inner fender going straight ahead over mild to moderate bumps. Other FABO members report no problem with this combination. From my experience, I wouldn't recommend anything larger than a 235/60-15 wheel/tire combination. Right after my test with the 255s, I called Stockton Wheel and asked what their recommendation would be for a stock Duster/Demon with BBP disk brakes using cop car wheels.. It was a 235/60-15.
