You should 5.0 the other sport trac

In the garage i have a 351w stroker and 2 warmed over 400's . I do have a 95 5.0 roller in a spare truck but I was kind of saving it for my 1970 bronco. The 400's won't fit in a classic bronco and even a 351w is tight without a body lift or cutting a hole in the hood

These 4.0 SOHC motors are big up top I wonder if a 400 would fit in an explorer chassis?

The 400's are great motors easy to make 500 ft lbs of torque just off idle with a mild cam but the exhaust would be a problem i think. Tranny would have to be a T-18 or NP 435 thats all I have laying around . I think its too much work to do on someone elses truck. Rigging up a clutch pedal and linkage If I wind up owning it somehow I might try.

If I do pull the 4.0 I could try dipping a carbed V8 in just to see what major problems will arise.

Myself I only like fords that predate GEM modules , its hard to see how to get stuff to work without all that crap.

Whew, the 400 is a huge engine, that won't fit in a newer Ford without tons of cutting and fabricating. I have the pieces to build one, including a machined block that has screw in freeze plugs, and four bolt main caps. That was an old project for a 70 Mustang that I didn't own long.

The 302 is the best old Ford engine that easily goes into the Explorers. Ford made them; so you can use all OEM parts versus fabricating many things for any other engine. You could leave it carbed, yes, but the EFI stuff is all worked out and runs much better.

For ideal upgrades, look at newer drivetrains, most are small enough, and all are far better on fuel, have more power etc. The 3.7 NA one from 2017+ is my wish choice, the engine weighs less than 200lbs, and it makes 275ish hp, 30mpg in the models that have it. Nobody has gotten 30mpg with any older Explorers, Al Aldive made a 30mpg thread and he tried hard with his 1999 4.0 SOHC. I bet the 3.7 NA would do it with 3.08 gears and the stock six speed.

Here's a rare 400(with SBF rear bolt pattern), mounted to a Tremec. Note the block size at the rear(top), see how much taller it is than a SBF there. The 400 has a 10.2" block deck height, the 302 is 8.2", so a 400 has the heads 2" higher than a 302 does. Those Cleveland heads also have a unique port bolt pattern, no header or manifold would fit a late Ford SUV. You'd be fabricating for a long time.

the 400's look big but aren't much bigger than a 351w if you think about it . But yeah, nobody makes any useful header for those m family motors specifically for newer chassis its a dead end unless you can stumble over something that just happens to work.

Even in a 78 the headers are annoying , the headers on the 400 in my 78 are over 30 years old and I've probably hated them for at least 25. They will outlive all of us though they didn't mess around I think they are hooker super competition 1/2 inch thick flanges with that eternal white ceramic coating. Id hate to see what those go for now

351W based stroker motor would be the easiest way to get a lot of power under the hood. Add a blower for some low rpm tire smoke

The 351W does have the W heads so Explorer type of manifolds can be possibilities, but still fully fabricated. The 351W is a 9.5" deck block, and the oil pans interfere with the steering rack. That's been tried at least twice, the pan had to be fabricated, and the AC box cut way back. I think the work to make a smaller late model V6 fit would be easier to do, and still have AC etc. It doesn't take much with the late engines to push the power up more than they already are. The OEM turbo's likely won't fit, they all seem to be mounted low next to the engine, so those probably would be hard to move or emulate.

The surface angle of the exhaust side of the head is a disaster on the cleveland family motors as far as fitting headers to late model chassis. Even if you decided to make headers yourself you are screwed because the cleveland flanges would be set up for huge primary 2 inch or bigger pipe compared to "big" 1 3/4 or 1 5/8 windsor primaries. The windsor stuff will tuck in closer to the block too.

Exactly. I remember a new guy on a Mustang forum who tried to modify a Windsor header to fit 2V Cleveland heads on his 302, in a Fox Mustang. He was surprised by that huge angle difference. He thought he was going to just cut off the flanges and weld on new ones he got for the 2V heads.

There is plenty of room to mount the engine in the bed.
