I traded some parts and got a fresh 360. The guy I got it from didn't know much about it but he gave me the phone to the guy that last drove it, he had it in his 70 Challanger with a 4-spd behind and he said the engine was strong and fun. He bought his Chally with the engine in it and the seller said it was rebuilt but didn't know much more.
I put it in and took a converter from my shelf that came from some 360 (with two weights on). It vibrated badly so I thought it must have been internally balanced when rebuilt, so I took of the weights and thought everything should be fine again, but it still vibrates... Not so bad as it did with the weights, but too bad to be good.
Any ideas?
