Close cooling + Neautra salt or just one or the other?

[dannieboiz]

I'm currently working on repowering my striper and already have a new Neutra Salt flush system but at the same time, I'm looking to add FWC to this new setup I'm getting. If I have FWC, does it help or even work with Neutra Salt or just install the FWC and call it a day?

What engine and drive? What year? The manufacurers don't recommend installing FWC systems on engines with 125 hours or 1 year of use. They tend to clog up the side of the heat exchangers you can't clean out.
The neutrasalt systems can only be installed on the suction side of the raw water pumps in order to work.

At this point, I'm ordering a reman long block from a company in the west coast who's supposed to rebuild engine for the state of washington then buying the bolt ons as needed. I've already got intake, HEI dist. bell housing, coupler and intake manifolds. So technical it'll be pretty much a new engine. Instead of ordering a new FWC kit, I'm going to buy a used heat exchanger and the brackets.

Just replied to your other post, you do have the SX drive, and you can use the Neutra salt system along with the FWC system. The NS system will prolong the life of your manifolds and risers.

Thanks for all your responses done. I'm actually very relieved now knowing that the current drive on the boat is an SX. I guess there's no reason to swap it with the older dog clutch OMC drive.

The current engine is a Ford 302 and I'm getting crazy mix inputs on whether to go with with a 351 or a 350. I'm most likely leaning toward a 350 since I went crazy on purchasing a bunch of stuff for it.

Just remember when going from a Ford to a Chevy, you need everything, that includes all of the fuel system, engine, exhaust system, ignition system, flywheel, coupler, flywheel housing, everything, nothing is interchangeable. With a 351, you can use the flywheel cover, coupler, distributor, wiring harness, carb, etc. etc.
Think about it.

Re: Close cooling + Neautra salt or just one or the other?

my mechanic recommend that I replace the whole engine since things are extremely rusted. He said the things that we can reuse is the distributor, water pump, power steering pump, bell housing/coupler and flywheel.

Here's a list of what I already have for a 350 engine.
-Bell housing
-Coupler
-Flywheel
-HEI Distributor
-Intake Manifold
-2 sets of Carb one of which is a 600CFM Edlebrok
-a set of brackets and pulleys, Includes 3 groove crankshaft pulley, 3 groove water pump pulley,and 3 brackets for power steering pump and alternator.
-Alternator
-Water pump
-I'm picking up the heat exchanger next week

I can reuse my power steering pump

Things that I know I'll need is Exhaust Manfiold with center rise, my current manifolds are straight but most of the ones I've seen have a 9 degree bend outlet. Does that matter?

I'll probably need the ignition harness but then that's only 3 or 4 wires which my mechanic can probably figure out since he's done ford to chevy conversion before.

What else am I missing? I'm waiting for a call back from the engine rebuilder on Monday and would probably order my long block at that time. I'm also ordering the oil pan, and all the covers from him for the block.

Wirhout actually being able to look at what you have, I wouldn't even want to guess what you will need. But it sure sounds like you have a good start on the 350 setup.

Not sure what you mean by straight, but even the Ford engines had center rise manifolds and risers. The pipe behind the riser that goes to the Y pipe is probably different as well.

Re: Close cooling + Neautra salt or just one or the other?

Not sure if you can tell with this photo, but my riser goes up and then 90 degrees back.

While these risers here for a 350 have a slight downward bend to it.

Re: Close cooling + Neautra salt or just one or the other?

cause the risers in the picture are mercruisr/marine power style risers, the gaskets are 4.3L v6 style.
all the risers for engine pakages sold with an SX drive were the same regaurdless of who made the block assy.
manifolds were different due to cyl head configurations but the riser stayed the same.
dont know about the Y pipe.
best I remember the ford pipes were narrower.
you may wish to measure riser center to center on the chevy block then measure your y pipes before installing the engine.

When going ford to a chevy nothing will interchange, not one single nut or bolt.
Your mechanic said to replace the engine because it's rusty? It doesn't look so bad to me, is the motor blown, block cracked, water in the oil, whats the deal? you took a BIG step backwards by buying all that Cobra stuff and a Chevy motor to boot.

Also, HEI dizzys aren't USCG approved. Not for use on boats with a engine cover.

Re: Close cooling + Neautra salt or just one or the other?

From the top side it doesn't look bad but everything beneath is extremely rusted. I think it's more labor intensive to try to remove things and clean it up. When we tried to remove the starter the bracket just broke off. We're going to remove what we can and sell it to recoup some of the money spent on the new engine. Since we're gonna get another engine dropped in, we're just going to get something for the long run. The ford parts are harder to come by but there are a bunch of the 350 parts and they're cheaper and that's partially why we're leaning towards the chevy at this point.

Be careful, HEI stands for High Energy Ignition and is also what the Delco EST distributor is called. Even the old coil in cap HEI distributor is now manufactured in a marine configuration by one company. But it's still a bad thing to use an automotive distributor of any kind on a marine engine unless you know for a FACT that it meets the CG specs.

Re: Close cooling + Neautra salt or just one or the other?

How do you tell if it's a marine disti or not? The guy guarantees that it's a for a marine application. I remember asking him twice and reconfirming right before I took off.

I stand corrected. found a couple for marine HEI:
