First off, never beat a damper on. You could have damaged the thrust bearing, who knows you may have. That damper looks like it’s made wrong. Get an American made damper. Do some research for your application. This would really be concerning me too.

I'd measure the snout of that 440 source crank versus a stock crank.

Why not use the stock 440 balancer that you already have? This engine build goes back 5 years (which happens to be when I bought the balancer). I have no engine building experience so a distant family member (through in-laws) offered to build it for me. He got as far as getting the rotating assembly and camshaft installed and then he suddenly passed away. The engine has been on the engine stand in my garage ever since so I am now trying to finish it up myself. I got the heads, rocker arm assemblies, distributor and water pump installed. All I have left at this point is installing the balancer, pullies and intake and I can then put the engine in the car. To answer your question about the 440 balancer, the guy who was building the motor suggested I get a new balancer since everything else was new (with the exception of the block) which is why I didn't use the 440 one.

I was told not to do this as it could damage the threads so I assumed it wasn't safe.

I honed mine ever so slightly by a machinist I honed a few dampers before with zero issues It doesn't have to be THAT tight of a grip on the crank. Gus

If it doesn't have a tightness to the crankshaft snout it won't absorb the vibrations it needs to do it jobs, way better to be tight than loose (just like your G.F. )

See if the 440 balancer will fit and work. Try it to see if the pulley alignment is correct. If it works then no reason you can't use it. Nothing else, it will show you what a proper fit looks and feels like.

Here's an update on my balancer problem. I got a balancer installation tool from Autozone. I heated the balancer back up again in the oven, oiled the crank snout, seal and balancer inner bore and slid the balancer on the crank. Attached the tool and pushed the balancer on as far as it would go. It went on 3/32" further than the first time. There is still about 9/32" of the balancer bore showing and based on my calculations it should be 5/32" if the balancer was seated all the way on the crank. So it would seem the balancer should still go on another 1/8". The pulleys are still no where close to lining up and even if the balancer was on the additional 1/8" the pulleys still wouldn't line up. They are a matched pair taken off of a 440 and the water pump and housing are MP aluminum parts. The forged crankshaft is from 440 Source. I also wanted to mention I have a stock 440 balancer that I compared to the Summit piece. The bore is the same length and when you stand them both on their snouts on a table everything is the same except the body of the Summit balancer is wider but it does not affect the crank pulley at all. The face of the balancer where the pulley mounts is the same height off the table on both. I've about had it trying to resolve this. I'm thinking of selling the motor as-is and just buying a running 340 to put in the car. The balancer needs to be honed a bit because it's undersized , I've never had to heat a balancer to get it on.
running up my post count some more .

if it were mine, i would remove the balancer and look close at the crank snout to see if any galling occurred. then look at the balancer bore for the same. lastly, i would look at the key way to see if something was going on there.

I can’t imagine that no one has mentioned that the balancer is assembled backwards. look at the picture on the box that you posted in your first reply. the bolts are toward the back side on the box. the fact that the timing numbers are backwards should be a pretty strong clue…

i had to look at the pictures again, but it sure seems you are on to something ! thanks for pointing that out ! can this balancer be taken apart and assembled the correct way by the basic person, or does it need to be sent back to the manufacturer to have it corrected ? if i had it in my hands, i would try to take it apart and assemble it correctly. however, i have way more shop equipment than the average person, and i'm not afraid to ruin anything. that's how one learns things. i have learned more things NOT to do than i have learned correct methods of doing things.

If it was me, I’d scrap it. Too many issues. First you beat it on, you may have damaged the thrust earring, second, misaligned pulley’s, third, numbers on the wrong side, Hope you straighten things out.
