I think I found my vibration problem

Ok. Not being argumentative, just continuing the discussion.

You say you pulled off a balancer that had the weight on it. Did you run the engine with that balancer? Was it vibrating with that old balancer?

Have you LOOKED at the crankshaft to verify (there's that word again) it is cast, or are you assuming it is cast because you pulled off a cast crank balancer?

What I am getting at is, if you are going on the assumption it is cast because you pulled a cast crank balancer off, you may still be able to fix the problem with the right balancer/flexplate.

I think if you have not verified the crank with your own eyes, it's time to think about pulling the pan.

Lets not get caught up with all of this yet: ("Lets assume that this guy who put this engine together didn't balance the engine, which I can almost know for a fact he didn't.....")

Since we have not verified for 100% SURE which crank you have, lets ASSUME this can still be fixed rather easily and cheaply. Doesn't that sound better than possibly jumping the gun?

I think at this point, pulling the pan is the way to go. We can help you identify which crank you have. That's no sweat.

Yup. So many things in question. This is

RRR, I pulled off the factory balancer as pictured in post # 46. The cone damper. I replaced it because I thought it was bad. Motor did vibrate when it was on. I replaced it with the 200-1128 and I left the weights on. As far as the crank goes, when I bought the engine, it had not been apart yet. It had the cast crank damper on it. I took the crank to the machine shop to be checked when the engine was tore down. What came factory in that engine is what should be in there. I don't imagine he switched the crank on me. Have I verified the crank personally since the engine has been in the car, no. At this point I am not going to pull the pan to verify this while it is in the car. I don't think It will come off while in the car. If I pull the engine to verify the crank, it will be gone through. I am almost sure that is a cast crank. I will not be pulling the engine till this fall. I will check it then to make sure. If it isn't a cast, then I will go from there.
