So long story short. I bought a used block and crank offline with some aftermarket rods and pistons. the guy told me that they were F20 set up. so i looked up the parts and they said honda parts so i did not look too far into it. I recently checked the rods and realized the rods were for an AP2 motor. I have the crank out of the block and am trying to figure out if it is a AP1 or AP2 crank. If its an AP1 crank then he just ordered the wrong rods and I can just exchange them.

Please let me know if there is a set of numbers that matches the crank. My block is getting sleeved right now and I just need to figure out what crank i have to match it to the rods and pistons.

please advise.
