Is the 94 GMC 350 engine same as 91 Chevy 350 engine.
350 engine in 91 Chevy has gone bad. Have found 94 GMC 350 in great shape and wanted to know if the engines were same and could be swapped out without having to change anything else.
they are pretty much the same. The only main thing is a 4x4 oil pan is different than a 2wd one
just take the oil pan off yours an swap with other 1 while u have the pan off do ur self some good & put a new oil pump on
