Here we go again. I have a .040 over 454. Around 550 hp with 570+ lbs of torque. OK, Now with the Holley Alum Heads and after much work on three different engine building programs (Chrysler) and my engine builder back in Detroit we all argreed to run Hooker Super comps, 2" primarys into a 3" collector and 3" all the way back with Flowmaster Super 40's.
Now the fun begins, I realize that the Super 40's don't flow (cfm) as much as some other mufflers, but, "they scavange a lot better and two different magazines did a test on the new GM 572 inch monster and from running open headers to a 3" flowmaster system, they only dropped 3 hp over the entire range.
Has anyone put a 3" system on their C-3 71 I hope and if so how did the mufflers fit?
thanks a lot
