I'm after a cam that will give me a LITTLE LOPE, not sound like a funny car. It must work with my A/C, auto trans (175k converter), and not shake the welds on the car loose. This is a cruiser, not a race car.

Oh, and I know where you can score a slightly used Thumpr cam...

With your higher compression you could even use a bigger cam. It's the wider lobe seperation that reduces the overlap and helps the engine idle smoother. I would suggest the Hughes HEH1928AL cam, 219/228 duration @ 0.050, 0.489"/0.524" lift, 111 LSA installed at 108. This would compare to the 262 duration Voodoo cam, 220/226 @ 0.050", 0.475"/0.494' lift, 112 LSA installed at 108. Or the Comp "XE262H", 218/224 @ 0.050", 0.462"/0.470", 110 LSA installed at 108. Going with the next larger sized cam you may have to run a higher stall converter, and/or more gear.

Mine has this MP Purpleshaft cam in it, and it's perfect for this motor. http://www.summitracing.com/parts/DCC-4452761/

I have a Scott Brown 268/285 in my 9:1 360, it's the same way, sounds mean (for the street)when cold , then tame once it warms up. '68 Barracuda with 9.5" converter and 3.55 SG. When it ran 13.75, it was suffering from fuel starvation, undiagnosed at the time. Want to get it back to the track this spring, should be 13.5 or lower if I can hook.

Hoping that this should make some good power, idle with a bit of lope to it, but nothing wild. Will be using a stock stall converter, with 3.23:1 gears. . . .
