I'm still hanging around reading and learning so I want to thank all of y'all for some great info i have soaked up.
But now I have a new question.
I have been looking at crank kits for my 88 1pc seal block.
Heres my question: Are all OEM 350 NOT internaly balanced? My 88 block IS internaly balanced is it not?

Do i need to rethink something here?
