Anyone here have experience running a tri-power on a big block? Thoughts on tri-power vs q-jet? Given the truck is a mutt I could care less about numbers matching, stock, etc.

ekneen:Just a word of caution>67-69 3x2 Int. Manifolds came 2 ways. Round Ports(Which I suspect you got) and Rectingular Ports for the High Horse engines which will not work with your heads. I would keep the Quadrajet for drivablity and less leaks. (All Holleys leak in good time)JMHO-Larry
