I have no idea what OBD1, OBD2, spider injection or mpfi is. I am hoping that if the engine is good (not busted from the wreck) so I can put an old school manifold on it and a quadrajet carb. That is if it has a distributor (pretty sure it does). If not I'll either sell the engine and trans or trade it for a older one. All this drive train is for is my 67 International p/u project. When wrecked last month the engine had only been in the truck for a week. It was a brand new rebuild to replace the burned up v6 that was in it. I have 300 bucks in it and figured I could sell the rest of the truck for scrap and get my money back. Pretty cheep drive train for the 67 project! I should have pile of parts (AC compressor, dryer, electronic breaking system, etc.) to give away that are in good shape also. I'm trying to save the wiring harness too. Is there a place on line that shows how to remove the fuse box from under the dash so I can pull it (harness from the engine side) back into the cab?
