OOPS!- - - - - -I lied! The GMC engine with the factory original filter setup is a 228 that's stashed away in a spot that's a bit difficult to photograph. I'll move it out to a position that's a little more accessible, and shoot some pics in the next few days. The plumbing on the GMC's is definitely different than a Chevy engine.
