- 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..
To start with, the engine in my '73 Mach-1 is a 4v Cleveland. If I keep the small block, I'm thinking of a 393c making around 450ish hp. This is a street only, daily driver. I'm thinking:
393C, 228/234 @ .050" hyd/roller cam, Edelbrock air gap intake, holley 750cfm, Sanderson shorty headers and 2 1/2" ,full length exhaust. Should I use the 4v headers or would that be to much head for that particular setup? I'm only asking because I've been told that the 4v heads are better suited for high RPMs. I'm planning on a tremec 5-speed with 3.50:1 gears.
