Would Altanator off a 79 ford 351 fit a 91 ford 351?

I don't know if it will fit but I believe you need a marine alternator or you could go BOOM!!

No thinking about it......that would be inevitable. Marine Alternator only.

It was a marine Altanator. It was bought for a 79 s&s.

Does it have an internal or external voltage regulator?

Appears to be a classic 10si Delco marine alternator. That should work if it will fit.

Ok I hope so I paid 35 for it on eBay. I need one. I guess if it does not fit I can sell it on here.

Or craigslist. Should be good for $50.
