Heat exchanger help
Re-powering a 89 25' marlin cuddy cabin I just picked up. Going to convert it to efi using a chevy 4.8l ls about 20 more horsepower and 30 lbs more torque than the 5.7 that was in it but shouldn't kill the alpha 1 gen2 that's on it. Trying to decide what heat exchanger size wise will work. This if my first off shore boat all other boats I've had where river/lake boats. Any help or ideas would be great.

there is a place in NY that sells aftermarket units at decent prices, been using a pair for well over 10 years now, can't remember name right off google it...something cool I think, going to be a $$$$ swap because of all the special parts required

I'm going to document the swap shouldn't be to bad price wise think I should be able to do it for 4k or less and have fuel injection keep the same cruise speed the boat had and use less fuel.

Manifolds are 250 each risers are 170 ish if mine won't work on those manifolds. Starter and alternator have a friend that can rebuild the stock units to cost gaurd spec. Working on a Re-power with a heat exchanger to sell for carb 350 to efi swap for around 5k
