I know this is an old thread but now that you seem to be a master rebuilder of these engines have you thought about adding some performance upgrades to them? From the look of the heads they could handle much larger valves and do they really need 4 rings on the pistons? Knife edging the crank to make it lighter and blueprint the rods too. Not in the sense to make it rev higher but to increase performance at its regular rpm range. Has anyone stuck the massive 472 with its 5" bores in one of our trucks yet?

My 65 had the 305E behind the Powergilde, was there an adapter plate needed to mount the glide to the 305E? I know where one is...can it be used to bolt other autos to it?
