Hello,
I am going to do a complete Morana build on this engine, as well as various suspension and drivetrain modifications that I will make other threads for in their corresponding places. Reliable performance is the theme to this build. I am aware that I may save time money and hassle by just swapping in a V8, but I want this truck to be the best it can be with an OEM block. Everything will be assembled by me and according to Tom's expected gains, finished, the engine should yield around 500 ft lbs and ~400hp maybe a little less(with a M112 SC). However I don't know s*** about tuning. Reliability being key everything must be submergable. I can build it but what I want to hear from you is precautions I should take with the electrical systems to resist water, what I should do about the PCM, and this may be the wrong forum but I have had no luck finding a company that makes a manual transmission that will "bolt on" this build's expected completion date is 2024. So no rush I'm going to do a frame off restoration, new interior, wire harnesses, lines, bolts even, and powder coat everything for rust prevention. I can post a list of parts if requested but it is basically everything tom Morana makes for the 4.0 V6

Just a note: By more than doubling the horsepower generated by that engine block, you are absolutely not gaining any engine reliability.

You will be pushing the abilities of parts and systems very much beyond their design and significantly reducing the engineering margins, and this will result in greatly increased wear and tear, and greatly increased chance of failure.

I'm not saying that you're making a bad decision, but I'm stating emphatically that you will have a dramatic increase in the amount of maintenance and the risk of breakdown.

I've considered what you are saying and have built race engines in the past and have found that the block was never an issue, this was Pontiac v8s though, and I feel and hope that the cast iron ford block will behave the same. But if the block which is the only part carried over fails then I will opt to put in an old 351

I also should have stated that the supercharger is up in the air and may not be installed and if it is it will be at a low boost. Naturally aspirated may be my choice but the decision will be made when the decision has to be made

It's not specifically the block that will be affected, but the engine system as a whole.

But, as you indicate you've built high-performance engines in the past, then I'm sure you're familiar with the increased maintenance needs, and have factored that into your plans.

Sounds like a fun project!

If you look up the word Reliable then there should be a picture of the Cologne 4.0l OHV engine there, it really was one of Fords better engines, good power and reliable, V6 version of the 302

One flaw is the head casting/design, and no way to fix it, the heads did crack between the valve seats when engine got too hot.
That would be my only concern about a "build" for extra power, you pretty much have to raise the cylinder temps when you raise power output.
So get the biggest water pump they make to circulate coolant, lol.

Might even look at that "waterless coolant": https://www.evanscoolant.com/

The heads are not stock Morana makes heavy duty heads and there stage 3s are:
STAGE #3:*
With the purchase of these heads, our best street porting job, larger replacement intake and exhaust valves, heavy duty springs OHV $1,700.00 per set*

I plan on adding and Eaton M112 supercharger to a 4.0L that I will be swapping in to my 91 Ranger that currently has a 2.9 auto. A 5 speed, manual tcase and 8.8 swap is in works to! My goal is 190 HP so I will for sure be following this build.
