Stock 318

That would be a Throttle Body Fuel Injection engine TBI. They use the in the tank fuel pump.

It is a roller lifter engine, probably with no eccentric for a mechanical fuel pump behind the fuel pump block off plate. With the TBI intake manifold ( unless it was carberated model, which I think was only 1985.)

Has 302 closed chamber cylinder heads, and more than likely the 9.2:1 flat top pistons with full floating rods. 318 internal balanced engine.

So lets reverse the question and ask what is this engine worth to you ? After we have laid out all the specifics about it for you.

M Body 318s used a carter 2bbl carburetor up thru 1989 the last year for the RWD M body. I think the EFI on the trucks started around 89-90
