Ken,
The only problem I see with the GM 6's is the siamesed intake port. That could probably be overcome with a port divider. F**d made it easier with their 300 6. As a side note my neightbor came into a treasure trove of Crosley motors. We were looking at them today and although they have siamesed ports, they could be port divided, and the head/cylinders are in one casting. If we could come up with some injector nozzles small enough ( only 45 CI) and turbocharge one of these ( 7 to 1 stock compression) we thought about building a belly tank or something and going to Bonneville. Probably a pipe dream but WTH it's fun.

I was OK but I got over it.
