I had a 302 in my boat many years ago I use many car parts on it and they were the same as the so called marine parts except they were a lot cheaper and they worked fine

An iron intake would be interchangeable but an aluminum car/truck intake would not be good on a raw water cooled marine engine.

An aluminum auto intake on a raw water cooled engine would be corroded away in no time but would not be an issue on a fresh water cooled (antifreeze cooled) engine. On a raw water cooled setup you would have to use a bronze lined marine aluminum intake if you absolutely had to have an aluminum intake.

If it is an automotive carb, starter or alternator you risk the chance of an explosion if used in a marine environment.
what I did when I put the starter in was seal the connections with silicone, I never changed carb or alternator but I did seal the connections any way, I did replace oil pan and water pump and used car parts, much cheaper

Depending on the application an automotive oil pan could mean certain death for a marine engine especially in higher performance motors. Marine pans can be made of heavy gauge steel or aluminum (making them less susceptible to corrosion), are typically higher capacity and include baffles and windage trays to compensate for the rough conditions that wouldn't be encountered by a typical car engine.
Yes, you can interchange some auto and marine engine parts but do your homework and make sure it won't be death to the engine or more importantly you.

I installed an oil pan made for a bronco it held 6 or 7 quarts of oil and had baffles in it, it was half the price of a marine oil pan

We searched for an oil pan for a 454 merc, cast aluminum......they listed for over a grand and no one had them, appearently they are not manufactured anymore.....we picked up a used one off of ebay for $300.
