Being that I want to run a carburetor which is why I'm looking for something besides a kegger in the first place, which means running a mechanical fuel pump, which means that having to use the LA front of the engine, I'm hoping I can run the 80s brackets and compressor.
How about running an aftermarket bracket setup like maybe bouchillon?
If you run an LA timing cover for a mechanical fuel pump, you can simply build out the rest using LA parts for the water pump, brackets, pulleys, and A/C compressor. That one works easy.
For anyone running an electric fuel pump and wanting the Magnum serpentine setup the easiest way is with a real Edelbrock RPM Magnum intake or a used M1 Magnum intake. I was looking into a 91 Dakota one year only serpentine setup that was used on LA 318 engines right before they got the Magnum engines but the compressor itself is not available. Check out this thread starting around post 58 for pictures of that bracket: Crosswind air gap clone and ram truck serpentine setup . That one would clear an LA intake or Chinese dual pattern intake if I could figure out where to get a compressor.
The other way is to build out the front of the engine as an LA setup and compressor, then use a conversion serpentine setup like CVF offers.
