I am better with wrenchs than computers so we will see if this works.I just fiqured out what a thread was.Any how I have a few vehicles but am working on a 1956 chev 3200 its all original never been touched california truck.It has a tired 235 in it and have an opportunity to buy a 235 out of a 1957 chev 4 door.My question is this my truck is a three on the tree the car is a three on the tree with over drive is this a easy swap.
