Black cover on the firewall. Remove that and there is a round plug

Yep. Mine was right next to the blower inside the cab. Turns out I was right on 0*. Thanks for the help guys.

I'm looking into a new exhaust system, 2.5". The high flow cat I found is 3", can I just use reducers and call it a day?

I'm looking to replace my oil pump. There are two available. One has a 3/4" inlet, the other has a 5/8" inlet for the screen.
How do I determine which one to get? Or do I just get one and then get a new screen to go with it?
I'm told both sizes will fit my truck.

Did GM change how the oil filter mounted on the side of the block in 94+? My neighbours 92 350 has a vertical oil filter where my dads 94 350 and my 95 305 are both horizontal, all the trucks are v8

Also the 92 has a huge oil filter compared to mine and my dads, thoughts?

The one is 2wd and the other 2 are 4x4 I assume?

Sorry all 3 are 4x4, the 92 is the odd duck, possible it had an engine swap from a 2wd?

When replacing the oil cooler lines I wasn't paying attention but by process of elimination I figured it out I think, just to be sure though, the top/longest hose goes to the top quick connect by the oil filter and the bottom/shortest one goes to the lower quick connect?
