Tripowers can be made to run. IMHO,what we have available now(tripowers) takes more work and most people take the easy way out by using a 4 barrell. I just broke into the 11's with my street driven, pump gas, iron head, 66 Tripower Ram-Air set-up(11.94/117) and I am in the process of making a few changes that should improve on that this Winter. If you do design a new intake, make it flow 300 plus cfm, that should be possible using the factory RA4 port size(Felpro 1233), with all the new heads coming out that would be nice. Also like others have said, a larger center carb(500cfm?) would be sweet for our 455's. By all means a simple/adjustable progressive mechanical linkage. Thanks -Jim
