That's an excellent reply Youngster, gives me some great ideas and numbers to work with as a start. I actually have an old PowerGlide w/o torque converter sitting in my garage but it's the old cast iron type ('61) and you need a fork lift to move it. The SBC and PG were to be used on a '54 Pontiac project I was going to start, but I just turned 50 and said to myself "do I want to spend the next 5 years grinding rust or start from scratch on a bucket I've always wanted?" The '54 is going up for sale and should fetch enough to buy the MAS body, tube axle assembly and a few more goodies.
I hope to dive into this after Labor Day and will definitely keep you in the loop. Anything else you can think of would be appreciated.
