- 1968 Coupe: 393w, TKO-600, Maier Racing springs, Global West suspension, Currie 9in with forged axles, 3.50 gears, Trutrac, Baer brakes front/rear
1973 Mach-1: 351c 4V, C-6, 3.73:1 gears and a long "To Do" list..
I'm not asking what is better, I am asking how one would compare the two. From what I have read, a dual pattern cam is preferred if you need to make up for poor flowing heads (right?). But, if you have heads that flow very well, would the longer exhaust duration work against you?
My 393w has 10:1 compression, Edelbrock air gap intake and a set of AFR-205 heads that have had a little work. The cam is a hydraulic roller 232/240 @ .050" .535/.545-112'. Now, if I were to pick a single pattern cam with similar characteristics, would I get a 232/232 @ .050"? Does the longer exhaust duration affect the power band or just help with scavenging? Thanks..
