While awaiting the replacement SBC, I've moved on to the brakes. I knew there was a problem as shortly after I put it up on brake stands I noticed a puddle of brake fluid collecting directly under the Master cylinder (M/S).
Best I can tell the power booster is an 8" universal single power booster and the M/S & Proportioning valve (combo valve) is for a 71-73 Mustang/Cougar. I'm going to post a few pics of the disc calipers as they appear to match what I see on Rock Auto for an 82 C10/Caprice/Impala. So it's looking like a hoge-poge brake setup.
Besides the leaking M/S and a power booster filled with brake fluid and not able to hold vacuum, the disc pads are too tight against the rotor making it pretty hard to hand spin the rotor. Upon disassembly the shoes look almost new and the rotors look to be in good servicable shape. It's possible the piston could be sticking in the caliper so it looks like a rebuild of the calipers are inorder.
Since I'm going to have to replace both the M/S and booster I'm debating whether to go with a new GM/Chevy booster kit (new booster, M/S & combo valve) or just replace the booster and M/S with the same Ford units. I've found a full Chevy kit on ebay for under $200 and can stay Ford for under $150. Either choice will be a rebuilt OEM or new Chinese....
It's hard to tell what the original rebuilder did and what some later owner did as I think this truck had an SBC at one time but I'm inclined to think the brake setup was in the original rebuild and that it worked. Unfortunately it no workie when I got it......
