With a 7.86 DCR and 0.043" squish, it should run well on pump gas in my opinion. Makes a nice torque curve from 2500 to 5500. Bolt on a set of 1 5/8" equal-length, long-tube, tuned headers and make 417 hp @ 5500 and 440 ft/lbs @4000 through the mufflers. Then, bolt on a 750 vacuum secondaries carb and make 426 @ 5500 and 446 @ 4500. It just gets better and better. Nice combination of parts.
