I have a gen VI big block which apparently has the wrong balancer on it. When the timing mark on the balancer is lined up at TDC, my #1 piston is about halfway down, and the #8 and #5 pistons are at the top of their strokes. I'm going to pull the balancer to make sure the key didn't break, but I'm thinking it's the wrong balancer.
The issue is going to be figuring out which balancer is right. This is a non-vortec engine. The casting number is from a gen VI, 12550313, I have a six bolt timing cover and a fuel pump boss, making me think it was sold as a block only. The issue is that I do not have a roller cam. I thought all gen VI's had a roller cam. Either way, are there different balancers for this engine, and what do I need to consider to figure out which one is right? I guess there's even a chance that the crank has been replaced, so what would be the right way to figure out which balancer belongs on this engine? Or should I maybe just remark the balancer on there and call it a day? To the best of my knowledge, this engine came from an ambulance built by Workhorse. Don't know if that's true, but that was the story when I bought the truck. And since I'm sure someone will know, based on what I described, do I have a gen VI or a Gen V? On a slightly different note, why can I not find a crank pulley for this engine?
