I'm still searching for a good engine choice for my eventual build and I can't help but to consider the 4.0 (especially in its high output trim).

There are several available in the local scrap yard at all times. The engine is known to run up to 300,000 without needing a rebuild. The HP is about 190 and torque is about 230, which should be plenty to get a 1500lb locost moving. Being that it's a straight 6, fitment shouldn't be an issue.

But the question is, has anyone done it or at least started it?

I think straight sixes take some effort because they are very long. I've seen talk about them here, but not sure there is a log with real progress...

From a quick search the general consensus is the engine is 32" long and 18" tall. Will that fit into an +442e?

The 4.0 is a nice little beast of a I6 but it really has some down falls unless you want to go the stroker route. The timing is very limited so boost is not out of the question but not easy. 190hp and 210ftlb~ out of a 4.0 is kinda blah. Strokers now there is some real power there 300+~hp I beleave the 4.7 stroker kit makes 400~. Had a 4.0 in my 96 Cherokee. I think there are better options out there. Two thoughts here if you are searching keep looking IMHO, if you have one dive in. Also the AW4 auto trans commonly paired behind the 4.0 HO is stupid bullet proof for manual I think it was the T15 was the most sought after. Mine went 130k with the last about 40k lifted and beat on off road.

the power to weight of the engine is not really sporty and i am not sure it would like the hight RPM that a sport car usually get to play with, its desinged as a truck engine, max torque is under 4000RPM.. and i am not sure about oiling in hight corenering G force.

i would look for something more car oriented!

Maybe not a concern, but the MPG in this engine are quite poor if I recall as well.

They are also astronomically heavy.. If I was going to go with an affordable straight 6, I would either go bmw m50/52, Mercedes m104 (though harder to come by with a manual gear box), or Toyota 7me/7megte. The m50/m52 is certainly top of the list there for me, as the power to weight is quite good, there is a strong aftermarket and those motors absolutely love boost.

My first post here. I have been trolling around looking...

So,... Will an inline 6 fit into the 442E?

I will be building mine around the "Leaning Tower of Power".
(Seriously! )

If a domestic v8 will fit, most domestic straight sixes should fit also, the sticking point being the height of the aircleaner over the valve cover. An intake that drops down or side draft carbs should cure that.

A slant six is more compact then most straight sixes.

The problem you'll run into with the jeep/Chrysler/amc 4.0/4.2 - Is that the intake and exhaust both coexist on the same side of the head, and even use the same mounting bolts.. It would be difficult to run a drop intake on that configuration. Your best bet would be a custom manifold, with a rotated throttle body.

Yeah, I was surprised how many domestic inline sixes are not cross flow and they either put both on one side or the other.

That particular motor has a pretty low intake relative to the top of the valve cover; at least the ones I've seen, so there would be no need except for eliminating any spacers below the carb or maybe milling the carb mounting surface and a custom air cleaner. It is all pretty "iffy".

Forgot about this slant six powered lotus:

Pre-fuel injection, an inline crossflow had almost unworkable fuel distribution issues, especially with temperature change.

Also there is no inherent benefit to crossflow- it is, in fact, an ad-man's term... one which betrays a sorry lack of understanding as to what goes on inside a chamber!

Not you! I just have a huge peeve with that crappy term "cross flow"

^ Jaguar remedied that issue by just adding more carbs
