Perhaps there are different 318 poly blocks. Maybe my 318 poly engine is originally from a truck? The oil filter that the Autozone gave me STP s8a screws into place but needs to be much wider to seal to the engine block. I think I found an adaptor on eBay that may fix my problem. What do you think of this? I would much rather have the filter that came on engine originally. But maybe they don't make the old filters anymore. What do you guys think?

That's the kit I was talking about. It's a duplicate of the factory parts that let you run a spin-on oil filter on an A or LA engine, rather than the older style that used a thick metal cover and a drop-in cartridge.

There's also a right-angle adapter that's used where there's a frame or exhaust clearance issue with the straight-on adapter.

It's not a question of different blocks; any A or LA with a spin-on oil filter will have one adapter or the other.
