It is a 318 poly with an NP435 and a carter bbd. It does run. Previous owner had massive jets in the carter carb. I had been wondering why it ran so rich and went through many many things before I was able to figure it out by comparing the jets in that carburetor to another earlier carter bbd I had around. The jets must have come out of a big AFB carb or something because they are about five times as big as the tiny ones in my other carter.
I think the carb was just dumping fuel into the engine and may have caused via cylinder washing, the low compression in the engine’s number 1 and 2 cylinders. I kind of like the oddity of the poly engine in the truck though. After my initial confusion and dislike of the choice, I have grown to like the engine. No plan right now to put a Chevy engine in it but were I to do so, or done so right away, I would have been saved a lot of time, then and in the future as I try to work around the starter being on the wrong side. I do imagine in the far off future a Diesel engine in the thing but that would be very far down the road.
Right now it’s wiring, attempt to make it sound electrically, then on to brakes, potentially a new rear end, new windows and weatherstrip, and a painted interior cab. It’s all going to be a slow process though.
