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

All 300 flywheels are the same balance, but buy the one that mathces the year and trans of the truck it is going into as there could be starter issues between years (but i doubt it).

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?

Great, It'll be nice to get the Bronco back on the road.

I remember reading that the I-6 was the only naturally balanced engine other than the (I think) W-16.

P.S. I was born in B-Ham, cool place.

nah, there are a couple other naturally balanced motors. the 90* v-12 is (it acts like 2 I-6's) and a good amount (if not all) horizontally opposed motors have a natural balance.
