I am using an 89 block 3.75 eagle crank 1 piece main seal .060 Hyp pistons...yadayada... I think it comes to a 388 CI but that does not matter.

What flywheel or is there a special flexplate I need forthis thing. I have purchased one from autozone. I have 2 other 400 flywheels and plenty of 350 flywheels. What combination do you use.

Man any help would be great. I am really lost here. I think the problem is the 1 piece main seal.
Everything else looks great. I have a lot tied up into this thing and its stuck on a flywheel problem.
