A guy here just got his 340 back from someone in SC, Mopar Specialist built it and he went to put it in and found it had a small register for the converter ? 273 crank ? what years were they smaller
Probably so. I don't know the year breakdown on the registers without searching. He should ask about balance. They either used a lot of mallory or they found 340 pistons that weigh around 570 grams instead of the 735g that the stockers do.
