I bought a 1984 rebuilt 5.7 long block to replace my 1984 blown mercruiser 228 and am in the process of swapping everything over.

My current issue is the intake manifold. Its raw water cooled and been running in saltwater for 30 plus years. I have to assume the intake is close to done. I have corrosion on the water jacket ports to the heads that I am concerned about. I just bought a new q-jet and would like essentially a stock replacement.

2 questions.

1) Can I use a used on off a car/truck? Seem like in better shape and cheaper on ebay.

2) Mich Motors lists several pre-86 models. (2101, 2504 etc...) Any idea which one is closest to stock replacement . I run in salt water and need cast.

Go to your local auto wreckers and match up your intake, there are several variations of the 4 bbl intake, mainly choke set up, if you get one with egr just block it off with a steel plate.
