Jim, still no cam recomendation ?
My project MAY take a turn here...the friend that put the 502 in that other guy's '72 has the ZZ502 intake available (basically an oval port Performer RPM...NOT Air Gap), and a real Doug Nash 4+1 just fell in my lap for 1150 with the Long shifter and a Centerforce pressure plate, so that Holley 870 may end up on the car with a much better intake (and still fit under the stock hood with a drop base air cleaner)...we'll see how it shakes out.
IF these 2 things happen, I'll spend for a solid roller cam. I'm thinking Crane #138781, 296/304 ADV, 246/254@.050, .615/.636 on a 114, OR 138791, 304/312 ADV, 254/262 @ .050, .636/.636 on a 114...
