I had thought to offer to trade. But since his alternator is a bigger frame and hits the block it's not what I need.
I've talked to Marine HowTo. He sells a higher output alternator that will fit the 3208. Barely.

There are two issues. A single V belt can only provide so much power and the 3208 has only a single V. The back of the OEM alt nearly touches the manifold. So a bigger frame is not an option. 90 amps is about it.
There are work arounds. Convert the 3208's single V to double V or serpentine with after market kit then build a bracket to hang the alt way outboard of the block and manifold. Seems like a lot of trouble and potential failure points.
When I upgrade it will be to two of the above alts, one per engine. Then tie the two together with either the Balmar Centerfielder or the Wakespeed WS50O into the house bank. Charge the start bank from the house bank.
Right now one alt charges the house bank the other the start bank. The internally regulated truck alts while rated at 50 amps put out about 25 amps.
For me another issue, simple to solve, is my engines are "energize to run" the solenoid is a constant 7 amp draw per engine. That's 14 amps wasted.
25 amps out of the alt, 14 consumed by solenoids. Doesn't leave much for charging. So the gen runs whenever we're underway
