I agree with this. Just for a comparison, I have a 400 0.060" with stock rods, TRW forged pistons, CC 274XE cam (230/236 degrees at 0.050" duration) and stock 670 heads rebuilt, stock intake and 750 cfm 3310 holley. In my '65 with a TH400 trans and 3.55 rear, 2500 rpm stall converter, the car went 13.0 in the quarter. Pretty basic combo runs pretty good and is a great street combo. I'm not advocating that cam, but with 72 cc big valve heads and a similar sized cam the combo will work well. The 6X heads will have such low compression it will need something like the 2801 or 2802 cam from Summit. Just offering an example of what you can do on the cheap, the car used the cheap 3 tube headers also.
