Was a good engine with good power. Four barrel Holley, if I recall.Yes they did! I have worked on few of them over the years.
The older 413's had Carter AFB's, I think.

In reality, there are for the most part, no internal mods done to most automotive engines for marine applications. Most of the modifications are safety related to the fuel, ignition and exhaust systems for use in an enclosed environment, or having to meet Coast Guard safety regulations for marine applications.Axxe55,
GRANTED. Though the IRON DUKE is the only automotive engine (that I can think of) that is routinely used in commercial workboat applications W/O being built or rebuilt with "marine grade" internal parts.
IF you go down to the commercial fish docks on the TX coast, you will see any number of Iron Duke engines, which have had NOTHING done to them for marine applications, except being fitted with a flame arrestor for the carb, a marine reverse gear fitted to the engine & a "dry stack exhaust" installed.

I know someone posted the WW2 Jeep, but can't recall anyone posting the CJ yet. I would agree it's an iconic vehicle.
For newer bowtie-based motors, many builders will make the tolerances slightly looser for marine duty, due to higher loads and rpm.In reality, there are for the most part, no internal mods done to most automotive engines for marine applications.

The vast majority of all the "marine" engines I have been into for rebuilds or repair, they pretty much had stock internals, with the exception of purpose built racing engines.For newer bowtie-based motors, many builders will make the tolerances slightly looser for marine duty, due to higher loads and rpm.
But a lot of folks just run passenger car crate motors.

You’re probably right for 90% of the engines out here.The vast majority of all the "marine" engines I have been into for rebuilds or repair, they pretty much had stock internals, with the exception of purpose built racing engines.
Even the Oldsmobile 455 that powered my jet boat I had many years ago, other than the aluminum intake and Holley four barrel, and the water-cooled exhaust manifolds was stock internally.
