I was curious what can hold more boost? a nicely built DSS, 306, 331, 347? IO was thinking the 306 because of the greater cylinder wall size and strength, but i wasnt quite sure. Does anyone have a good idea? I would say a 9.0 compression or 8.8 compression on all of them, and hopefully in the neighborhood of 15-20 psi of boost. Sounds like a lot but its just an estimate. -thanx.
