I'm putting a mid 70's 300 in my 85 bronco and need to know if there are any balance issues between the two? I think they are all internally balanced but I wanted to verify that. The 70's motor was in front of a manual and my Bronco is an auto. Thanks
I know I can't use the flywheel, I'm leaving the automatic in. I just wanted to make sure the flexplate would work with the 70's block and that I didn't need to find one that was weighted different. I guess I worded it wrong. I guess I should have said is, are all years of motor balanced the same?
