This may be a dumb question to the more mechanically literate but can you elaborate on what a 4.3 might be? I assume that may be the displacement or model number but from what maker?

[imagine2frolic]

Is it fresh water cooled? If so why not Chevrolet, Advanced Auto, Pep Boys, or any other suppliers of short & long blocks

Try

Engines 1

or one of their dealers

Also Marine Engines: JASPER

for a rebuild.

a 4.3 is a gm 350 cid. with 2 cylinders missing....the only difference between a marine long block and one you put in a car is the brass freeze plugs...they are common everywhere ..........
