The 300 and the 302 use the same bellhousing. The only major difference is that the 302 uses a counterweight on its flywheel and balancer. The 300 is internally balanced, and uses a flywheel with no counterweight. Get a 302 flywheel (28 oz. or 50 oz., depending on the year of the engine), some 302 motor mounts, and have fun!

My bad, sorry for the confusion, I always thought an I-6 would have a different bellhousing than a V-8 would.

The small 144-170-200 sixes had a different bell, but the 240-300 big six and the 250 small six used the 302 6-bolt pattern.
