snorks are a must for deep water . you have to get pretty deep to get up over the intake but if thats what you might be doing get a good snore that goes up along the windshield not one that goes out the finder and stops . Also don’t forget the tail pipe .
As to the fan issue .
If you have replace the stock fan or your stock fan is an electric then you need to be able to switch it off . If your fan is a centrifugal clutch fan then there isn’t a lot of worry . Simply move into the water slowly “ goin in to fast will blow the fan apart “ . The resistance of the water will slow and stop the fan
It also is a good idea to electronics waterproofing . On everything that has current or produces current .
The best sprays for this can believe it or not , Not be found in the automotive industry .
Look at what the Radio controlled folks are doing with their models . These have much finer electronics then anything found on your vehicle.
Corrosion X is also a very good product for this . Also don’t forget your ECM .
Anyway , back to the subject at hand .
Now this may be off topic as an example but
Here is a photo of my engine in my 1970 IH scout 800 which fuel injected with a TBI .
Now , I will admit that I was a hard core carb man . Electronics frankly scared me for many reasons . However when I started studying ,as to the facts of the mater , my fears were mostly unfounded or in correct .
This engine was original carbed with a 4 barrel and from a Chevy Astro mini van .
She was balance and blueprinted , heads shaved , pistons are high compression forged and .060 over . Red line cam with roller rockers . Oil system is powered by a high flow pump which puts out 50lbs at 1000 rpm
Fan has been replaced with an electric , radiator was rebuilt with an aluminum core .
The engine is capable of 305 horse . Not a lot in compression to bigger engines but for a 4.3 its a lot . I mated this all to the original IH 4 speed trany
The point of all this is I was concerned IF a 2 barrel TBI would provide the capability in place of the Elderbrock 4 barrel . My worries were unfounded .
While I am still learning these systems , to say im impressed with the tuning ability of the ECM is an understatement .
Now there are aftermarket setups available but they run in the 1200 and up range .
So I did some digging to find out just how hard it would be to build my own system from parts basically starting from 0 . With an engine that had never had fuel injection .
What I found was that there are many locations that will lead you through the build , using WY , ECM’s . even wiring diagrams to show you what wires are actually needed and what ones are not .
They also lead you through setting everything up and tuning the system .
Start to finish I was able to build this system you see here in my off time , over one week . Swap it into my rig and have it running the following weekend .
Now with 16 engine , these came with a TBI so the hard part is already done for you as the injectors are readily available for you displacement. So all you would need is the TBI from such an engine . Then basically either get the engine harness from that vehicle.
OR update the harness and ECM from a newer one so as to have more capabilities concerning the ECM . Updating provides more programming ability and after market chips or as I said before , the ability to do your own programming .
Also by doing this you can decide if you want a fully functional setup or just the basic needed sensors. As you can tell from my photo I went with the basic needed sensors . As such the engine harness was reduced by near 60% concerning wiring
The engine runs fine , starts one the first crank every time even in cold weather . My MPG went up by near 10 MPG . I also have much better throttle response and power .
in this photo i had not yet finished routing the wiring so there are some wires along the fire wall that have since been routed through the main harness which is the one in the blue casings
