They will make a very good hot rod motor,I had one in my pro street 57 Chevy,And it would fry the 18.5's at 50 mph.And that was with stock pistons .I went with the stock pistons because every where's I called they told me they had to be custom made for about $1.000.00 so I deck the block and shaved the heads,and put low cc heads.And made a very hot motor with a really nice cam.I wouldn't build the 366. :thumbup:pasadenahotrod said:They are truck motors, not hotrod motors. Stick with the real thing, 454, 396, 400. You're not souping up an old Uhaul are you?
A blower is never a bad Idea, just make sure you do your homework, you are right about limiting the boost, detonation is more likely on BBC's and they don't like it when you retard the timing.6x6er said:Thanks for the great info, I never new about the spacer deal. If I were to find a set of heads similar to what you had mentioned, would it make sense to install blower as long as it could be limited to approximately 7# boost. Just wondering if the engine internalls could take the extra pressure. By reading what you two have wrote, it looks like these engines can take it as long as the RPM's are kept lower. I like the idea of the blower, seems to make sense for power and dollars. Still seems like a lot of figurin though?
