I am leaning heavily towards this cam, a few questions:
What carb and intake are you running?
What rocker ratio/valve springs too?
What is your static compression ratio?
What trans are you running?
What is your rear gear ratio?
Would love to know so I can tailor my build, thanks!
Dave and I have very similar engines. I use a Comp Cams Magnum 280H.
1. I have a 650 Speed Demon, 1 inch spacer on top of a M1 dual plane.
2. I have Crane rollers, 1.6 ratio with Mopar springs. good to .550 lift I believe.
3. 10.58 to 1
4. 727 manual reverse, 2800 stall conv.
5. rear is 4.10
Tires are 255-60-15, headers, X-pipe 2.5 inch exhaust MSD ignition
My heads are ported and have 2.02 valves. I would reccomend at least gasket matching the intakes.
My combo dyno'd over 400 hp and over 400 ft lbs torque.
