Well I will repeat this part:

If your running more than 500 horse, your going to need some serious tires or some kind of traction control on your COBRA. They don't transfer weight like many other cars do, which creates a traction problem. If you don't address that you simply can't put the power to the ground. Doesn't matter what engine your running.

67FEfastback makes a good point, at a car show I'll glance at a Windsor or a 385 series engine, but there really nothing to linger over. Just another motor, nothing to see here folks, move along. Small block Chevy, oh puhlease, I might not even glance at one, there everywhere and reguire zero imagination and a moderate budget.

Hemi, in whatever, well now theres something different, better take a look. Old Cadillac or Oldsmobile engine in something like a Rat Rod? Excellent choice, GOTTA check that out!

You can't ask an engine related question here on Club Cobra without getting opinions across the board, no matter WHAT the original question was. To think otherwise is clearly the ASSumption of a newbie!

Trap speed was 121, went down to 118. VERY tall gearing, shift into second at 65 mph, 2.0 0-60 ft time which didn't change (traction limited even with the tall gears, big or small motor). I'd shift into fourth just short of the line, hardly optimum gearing for a "drag race" setup.

700 horse is a "waste of time" as in ET at the drap strip, with street tires, loads of fun and very impressive other wise. A good number!
