Good info - why I'll request some help because the single in question here is a ProForm down leg DP body with QFT blocks. I need to pull it apart to get the specs on the blocks. I'll be switching to methanol later, but would like to have the gas carb at least in the ball park. A similar unit runs on the door car, first step is to jet this one like that one - may work even though the target motor is 100+ HP over the other.
