Im planning on installing the new engine soon and wh=ant to order and have everything on hand. Thanks.

 

Offhand, the only difference I can think of would be the flywheel...you'll need one to fit a two-piece RMS engine.

I thought 86 and up had 1 piece seals

 

yeah 86 is first year of the one piece rear main seal

good luck

 

Sorry to burst your bubble, but mines a 2 piece.

 

it is not an 86 engine then, id like to know year of your car and year of engine in your car right now,

and also what is the shape of your crank rear flange, is it perfectly round or flared out flat mounting face for the wheel ?

good luck

 

Well it came out of an 86 pickup. It was the original engine. I checked the casting numbers and it shows it being an 85. But I assure you it came from an 86. The truck was bought new by my grandfather, so I know what year it SHOULD be. But it is a 2 piece, I broke it down myself. So do I only need a diffrent flywheel? Thanks for the help. By the way, I currently have an l03.
