i have only had my truck for 5 days. when i traded for it the P.O. "thought" it had a 350 but wasn't sure.
i just pulled the casting number and the stampings off the front of the block. it is a 305. Not that i really have anything against them and the truck does run good but DANG IT!!!!
have also figured out that the lock up 350 trans has been replaced buy a plain old th350
