Yes , build it using what parts you have on hand , does the counterweights look like swiss cheese ?

I wouldn't run that engine without having the balance checked , possibly correct with a neutral balancer and sell that one off to someone looking for one, the two small holes aren't really an issue when it's going to be used to balance the engine anyway, easy enough to pound 2 piece of steel into it and tack weld them into place.


So the rest of the story is .... When I drove the car ,a 71 GTX 440 4spd car. It has a vibration but it also has soild / steel engine mounts with one of the bolts missing so I figured that was the source of the vibration.
When I pulled the engine to fix several oil leaks and repaint it I noticed the balancer and when I removed the pan and saw the rods in it , well , the parts don't match. The flywheel is a neutral balance. I posted what I found because I wanted to see if if this right or someone else has seen this. I think this is a parts mismatch . I think I'm going to install a new balancer, if the vibration is worse I'll put the 6 pak balancer back on.
