When comparing one-piece rear SBCs, are vortec pans/gaskets interchangeable with non vortec? Can I use an 87-96 pan/gasket on a 96-later vortec engine?

Some gaskets list as fitting 87 and later one-piece engines, while others only list 87-96. Same with pans. Straight dope anyone?

There is a difference on some year models....what side the dip stick is on.

Ayuh,......
I think the Dipstick swapped sides in 1979,.....

The Block didn't change with the Intro of the Vortec heads in 1996.......

Sooo,..... The Gaskets should be the Same from 1987 On......

The Vortec SB V8 pans are interchangeable with the earlier 1pc seal engines. The gasket is made a little different for the Vortec due to the plastic timing cover. Simply get a pan gasket for whichever cover you are using.

it was 80 that the stick moved, not 79

and the one piece RMS was in 86, not 87
therefore the pan gaskets go from 55-79

and 80-85

and then 86-95

not rocket science here

Ok, great. I'm winning a 1-piece cast aluminum marine oil pan on ebay for $20 brand new. That will look great polished up on my boat.

Off to buy gaskets for a 96-later 1-piece.

Fast 68, Let's remember the 55 blocks did not have oil filters cast into the block and the pan was different; therefore the gaskets are different. But, the "correct" amount of gaskets do come in the set to cover those blocks usually. Just a "technicality". BUTCH.
