So when I first got that motor I used it with a stock 440 truck flywheel, then I rebuilt it, and the machine shop balanced it with the flywheel, and they drilled the flywheel in a couple of spots to correct the balance with the l2266f pistons. So now I want to move that motor to my 77 Ramcharger, that is automatic, is there a way to match some converter weights to what was done to the flywheel?

I stopped into an another shop and asked if they could balance the flexplate, they are saying they need to knock the motor apart and rebalance the whole thing. If thats the case, I probably wouldnt put it back together with the l2266f's. I'll try another shop tomorrow.

Without knowing the original bob- weight used for the balance there's no way they can correctly balance it without taking it apart to get the actual weights. I love the smell of Deer guts in the morning, it smells like... VICTORY!

There should be enough material in the B&M plate to drill enough holes to achieve the same off balance as the flywheel.

Put the flywheel up in a wheel balancing machine and you will find out how much and where it has been balanced. Weld the same weight on the opposite side (180 degrees) on your zero balanced converter and you will be fine. It is important that you have about the same distance from the center, so measure the converter first so you know what distance you should use when you put the weights on when you zero balance your flywheel.

Kevin Ext bal isn't for six pack rods, it's a '77 cast crank motor. I assume the pistons are lighter than OEM and the shop removed weight from the flywheel to make up for it. The wheel balancer idea won't work. It only will tell you the degree angle and how much weight to add, you also need to know how far from the crank centerline to place it.
