It has stock crank, eagle rods, ross NHRA-IHRA stocker pistons, 750 DP holley, Victor Jr. intake, and gt40p heads with a good valve job. The short block for both engines are the same except for the cam lift. As my son Brandon said we have tried both and the 250 is a better combo.

Thanks Gary.

That's good to hear that the 270 has more cam lift and better heads.

It looks like the 270 is the way to go for a carbed/automatic class car.

Thanks for the info.
