Unless they are setup for salt water, which in that case they have a heat exchanger and are more conventional. They also have special carbs and fuel systems to keep fuel leaks to a minimum while in the enclosed engine compartment.

To add to these comments, carb venting will be different on a marine engine, too. Fuel vapors are heavier than air and will collect in a boat's bilge, so that must be avoided. Same for the vent on the fuel pump. It won't hurt to leave this stuff if installed on a truck, unless there are some unintended consequences we aren't considering.

Expect differences in the electrical system, too. The alternator and starter guts are typically sealed just in case fuel vapors have accumulated in the boat's engine compartment. Not really an issue with the open-bottom engine compartment on a truck or car.

Same with the distributor, too. The vent on a marine distributor is designed to keep any accumulated fuel vapors away from an ignition source.

You're usually fine using marine components in an automotive environment, but not the other way around.

This goes on the passenger side iirc..

I'm not familiar with that cam but when i punch that grind into Comps website it comes up as an equal duration grind for Chevy.
Someone must have ported the heck out of your exhaust ports for that grind to run well.
Do you know what valve sizes and compression this engine has?

I know it doesn't have 2 pick ups. Also I found that cam kit for a 429/460

Above, you said it had two adapters for the pickup.
No. It has an extended rear sump pickup and a mounting stud.

Yeah
Its a symmetrical (Chevy) grind on a Ford billet.
So given the ****ty flow of almost any Ford exhaust port and the fact that *that* cam has no more lift or duration on the exhaust than the intake lobes, I stand by my statement that I hope the engine builder ported the hell out of the exhaust.

I guess it really depends on what you expect, or hope to use this engine for.

If you're going mudbogging or pulling i suppose it could work for you, but it isn't going to be making a lot of power down low.

hmm.. I remember saying it looks like it's capable of running a rear pick up but I don't recall saying I had 2 pick ups on my 460. But if I did I didn't mean too .......................... and it's been to the machine shop and everything is new so I'm guessing it's been built correctly. I haven't torn into anything other than sliding the cam out.

Well im sorry if i misinterpreted the post i quoted.

The oil pump only has one intake, and *whatever* pickup can be bolted to it.
There may also be a port for pressure relief or adjustment.
None of us has any way of knowing what went into this engine.

I think you've been given some good advice wrt what might have to be changed. (not much in this case)
Manifolds, water pump, oil pan...

As has been said ~marine engines are ok in a vehicle, just not the other way around~
