Re: Random Chit Chat
It should be an ECU code stamp.
(At least that's how it is for Hondas) My block is stamped F23a1. My head is stamped P13-PF1 which is USDM H22a1 Years 92-96.
Not sure if that helps. Look up the RedTop ecu and vary it from the USDM ecu code. See if that's stamped anywhere on the head.
