I recently accuired a 327 (small journal) motor from my father in law. It was built with 12.5:1 pop ups and double hump heads. my problem is the thing sat for to long (6 yrs) and the crank is not in the best shape. Do i have any options as far as a 350 or 400 crank (easier to find) with out having to get new pistons. i whould really like to keep the pop ups since they are brand new. i dont know much about motors but i know the pistons and the stroke is differant. i guess i am wondering what the best and most coast efficant way is .
Thanks for any feedback.
