I have a 1944 model A that I have a apart to replace the crankshaft due to the splines on the clutch end being damaged. While I'm this far into it I considered doing a bit to raise the HP some. It has .45 oversize cast pistons in it and later rods with insert bearings whereas factory would have been the babbitt style for this year I think. Correct me if I'm wrong. Assuming these could be late A (gas) rods are they any different than the earlier ones compression wise? The head is an all fuel one by the casting number. I plan to have the cam reground for sure before it goes back in but what else should I consider doing to this to bump up the HP? I'm not looking for any crazy HP numbers like some of the pullers out there just the best bang for the buck with out spending several thousand dollars.
