Hey Marc (and anyone who knows better than me), did you happen to use an ARP balancer bolt? I was putting mine together today and noticed that the directions from ARP and ATI don't agree with each other (different torque and loctite vs ARP assembly lube). Curious to know what you ended up doing.
Also, you probably already caught this, but I didn't
The instructions also say that the alternator grounds through the water pump housing so it says to keep that mounting surface paint free. Not sure if it matters much or not, but I went back and cleaned that area of my block since I didn't mask it off before paint
