Picked this 63 413 engine today. Built 2/8/63 was in a old engine rebuilder shop. When business closed. Engine was stored outside under tarp so it is seized. Has rebuild tags. Says its 60 over. My questions for you guys are is this a industrial 413? It's has gear drive? I didn't have to give much for it. I would like to use it in a 62 300. I seem to remember hearing something about industrial motors turning backwards? Another question is will 361 383 harmonic balancers work?
