Was wondering if there is much demand for 413"s out there. Looking at a block with 516 heads. I would guess a 4.320 bore would get standard 440 pistons. Thanks for any information.
Both are marked 66 BB . Can't see any numbers. Got in a parts buy so no history. One has a bent pulley and turns freely. The other has a straight pulley but doesn't turn. Both have brackets. $75.00 each plus shipping.
