That horsepower is applicable to marine use. The issue with that engine and horsepower is cooling.

Re: Repower setup

Very true. He could bring a water tanker with him I was just surprised they could get that much hp out of it. I honestly don't know much about cat engines. Ask me about dt466's and i could blabber your ear off

The Cummins 8.3 has wet, replaceable liners. This is the only reason I want the 8.3 in a rat rod over the 5.9. That and the 1200 ft pounds of stock torque.

Liners for the 8.3

I can find 435hp Cummins 8.3 in fire trucks. If that is stock, add 25%, it will still run all day. Older 8.3's are like the old 5.9's. A few Allan wrenches and sockets under the hood gain you 10% to 15% at no cost.

At my naboring bus yard, every Cat 3208 has failed. Not a single 8.3 powered bus was parked due to engine trouble.

One more thing about marine engines. The camshaft and other engine components are set to make that power at a extremely narrow power band of under 200 RPM.

Compare power graphs of a Marine Engine beside a Road engine. Same thing for industrial engines in things like bobcats. The engine is tuned to make power to match the hydraulic pump it runs. And generators, ect

My bad...i thought they were the same as 5.9's. Don't get me wrong, i agree the 8.3 would be a better choice, i just could see where the op was coming from. Imho, the 8.3 is hands down a better engine. I would also prefer a dt466 over a 3208. Was just relaying the little research i had done. I also wasn't aware of a 435 8.3. Sounds like i didn't do enough research

Re: Repower setup

I would prefer the DT360 or the DT466 over the 5.9 in anything bigger than a one ton due to the wet liners.

However, around here there are ten 5.9's for every one DT466. So I have to stay with the 5.9's.

Re: Repower setup

Actually, a 3208 in marine trim was rated up to 475hp, for some crazy reason. Not sure if they made it much past 100 hours that way. If you can get it to stay cool, and not fog out an intersection every time you press the pedal, I think it would be a real monster.
