It’s best to figure out what you want out of your car. Street/strip or canyon carving/auto cross. Due to what you want out of your car the cam selection will be a little different, depending on power brakes, carb selection, DP or vacuum second. What heads and valve size, intake and such.
Currently my 72 duster set up for canyon carving / auto cross
340 .30 over
4-speed 3.91
Comp EX285HL, 241/247 at .050 110LSA
2.02 J heads,
Air Gap,
Holly 750
Vac brakes
The motor pushed 390hp on the dyno, but is not happy with a 4 speed setup.
I’m changing my heads to a set of Eddy RPM heads that are fully ported with 2.05 valves, ported Airgap, removing Vac Brakes. New cam solid flat 234/234 at 50 on 107+2.
I’m really tempted to drag the motor to Cali and run it on my brothers 901 superflow and see how these changes to the motor change the power / power band...
