I had one in my 61 GMC PU, My father rebuilt it over the summer of 74. It was a Massive engine, as big as a big block, I went through 5, 3 speed trannys, most of them had destroyed cases. It had the shifter on the colomb. I mounted a mister gasket floor shifter. Reverse was across from first and when burning the tires it would fall into reverse and push the idler gear out the side. then We put a granny gear 4 speed and I took out 2 rear ends, my friends said I got the wheels 3 feet off the ground. Yeah it was a big strong engine.

It seems to me that with 7.5 compression ratio you could shave the heads and boost it up to about 9 and gain some significant hp and torque without boost. Can you imagine the throttle at a streetlight?
