Big Block Oil Pan
 
2 Attachment(s)
I am working on a 1968 Chevy truck that came factory with a 396. The 396 is coming out for a rebuild and another big block will be going in to keep the truck going in the meantime. The current oil pan that came factory on the truck looks like a car pan, similar to what you would find in a Chevelle, Camaro or Caprice. I have an extra oil pan from a 454 out of a late 70's Chevy pickup but it has a bigger sump. Does anyone know if this style of oil pan will fit in a 68? I was afraid that there might be some interference with the crossmember. I attached pictures of each style of oil pan. Thanks

If that actually was in a 2WD BB square body then I don't see why it wouldn't fit. The front suspension is interchangeable. But that sump looks really big to me too.

That looks more like a marine or maybe big truck pan to me.

Thanks for your reply. The bigger pan was in a late 70's 1 ton 2 wheel drive Chevy pickup 454.

This is the Pan I used on the 454 I put in my 1970 1/2 ton Short Bed back in 2004, it worked fine, no problem. Good Luck on your Build

Here's my pan when I had my factory 396 (L47) out for a rebuild.

The 68 pickup Big Block 396 was the exact RPO L35 396-325 HP that was put in the cars, so the same oil pan. It had 10.25 compression ratio with closed chamber heads and 410 LB-FT of torque. The 69 was a 402 truck engine with open chamber heads and a different cam.

Maybe someone could snap a picture of their current big block in their 67-72 pick (wouldn't matter which oil pan) to give a reference???

The oil pan in post 4 looks exactly like the unit you are asking about....

Thanks for the replies and help everyone. We decided to find another car style oil pan for this project.

This is the same oil pan I have in my 68 truck.

Either style oil pan will fit in your 68 truck.
