NO it will not work.
WHY
The 2.8 pan has the front lip that connects to the timing chain cover.
Two 8MM fine thread bolts hold pan to t. chain cover.
When I do my 3.4 swaps, I retain the 2.8 original engine timing cover & pulley & oil pan as a complete unit.
The 3.4 pan is straight out (2.8 pan dips down) & also 3.4 is a one piece oil pan gasket.
The 2.8 is a two piece gasket item.
Pass on this option.

Er, Karl, you're thinking of the 82-86 oil pan. This pan used a two-piece gasket (rubber at the rear seal, cork for the side rails and front), and bolted to the bottom of the timing chain cover.

The 87-92 oil pan uses a "reusable" (although I wouldn't!) oil pan gasket, made out of rubber. It also has a different "slope", I believe, in the front, then an 82-86 oil pan.

I'm 90% sure of this... can anyone verify? I don't think the pan bolts to the timing chain cover on 87-up 2.8/3.1's.

When I bought one for my 3.4l swap, it said like 87/88'ish, and up 2.8/3.1/3.4l.

But I do belive ked is correct that the front lip on that thingie looks funny. Maybe for a fwd 2.8??

I know my pans dont have a front like that, it is more boxy with chamfered edges. Plus the front is damn near identical with the back flange wise.

Did yours have the one-piece rubber gasket? Or was it the cork/rubber 2-piece setup?

MY response/knowledge pertains to 1985 60* milss & prior.
The 3.4 examples I've worked with are the 1995 model year 3.4 engines.
Those two pans are different.
I wouldn't seek out a 3.4 pan as an alternative for a 1985 60* oil pan. Those oil pans are drastically different..

Seal I got was a solid 1 piece rubber, ribbed. I belive it had a metal "support" or some crap inside.
