302: two different bellhousings?
I was talking to a guy today that had recently swapped a 302 in to one of his older cars. He was saying he had a little trouble because there was there were 302's with two different bellhousings. Now that I've thought about that all day, I vaguely remember hearing that somewhere. What was the deal? Were the very early ones different, then they changed to the standard "small block Ford" pattern?

The 6 bolt small block bellhousings are the same as far as the bolt pattern, but the actual internal size of the bellhousing may be different depending on if it came frome a 28 OZ balance or a 50 OZ balance flywheel (in the case of a C-4 anyway - not sure about a C-6 or FMX). Most 50 oz flywheels have more teeth than a 28 OZ. More teeth makes the flywheel OD larger. There are aftermarket companies that make the smaller flywheels in the 50 OZ balance though.
