A viper t56 would help with the gas mileage if you had enough motor, the 2nd overdrive is .5:1

the 4.0 SOHC is the most modern cousin to the European 2.8 used in the Capri from 30 years ago. Its a 60 deg V . Ford V8s are 90deg and share nothing with the 4.0

Good thread Dale, you are well on your way to getting started. The 347 built with much better heads/intake/cam/exhaust will easily make 400+RWHP. That alone will take care of almost all V6's. Note that the exhaust is a huge problem, not solved with bolt on parts. That's a huge subject I'd rather address after I've built mine.
FYI, there have been people who 4.0's built with those 2.9 DOHC heads. It's not a good idea really, those head are not up to the flow needs of a 4.0 engine. It was cool to read about it and see the pictures though.

ohv and sohc are basically the same engine just different head setups.
They are both 30 year old technology.
Nothing wrong with old tech just not up to the same level as the newer 300+hp V6s

never owned an ohv so just quoting what I read..
____________________________________________________________________
4.0 SOHC 60 deg V6 & 4.0 OHV 60deg V6 Engine Differences:
The main difference between the Ford SOHC 4.0L and the Ford OHV 4.0L is that in a SOHC engine there is a camshaft sitting on the top of each cylinder head with the valves running directly off the camshaft. It doesn't rely on push rods, rocker arms, or lifters. The SOHC engine uses a jackshaft in place of a camshaft to drive a timing chain to each cylinder head. Three timing chains are used, one from the crank to the jackshaft, one in the front of the engine to drive the cam for the left bank, and one on the back of the engine to drive the cam for the right bank.
The OHV engine has the cam mounted above the crank. The cam and crank are joined in time by a timing chain. Lifters ride on the cam and push rods that extend to rocker arms in the heads which push the valves.

Ford used the OHV shortblock to create the OHC, with slight changes to the block mainly. The whole induction above the shortblock is all different.

I have a 2.9 V6 24v Cosworth engine back home... I wonder why they never offered that instead of the 4.0, it makes the same amount of power.

torque..
big heavy suv needs torque to get moving..
The Cosworth may make same hp but at a higher rpm and with little
torque on the bottom end. Makes a great sportcar engine but not so
hot for hauling the family and the boat to the lake.

ok, so I've just had a look at this and can't figure out the wire/circuit for the oil pressure sending unit...
any ideas? thanks

While its a different vehicle the weight was close to the same,
My LSC which weighed 4250 (almost exactly what my Explorer weighs) with me in it ran 11.7@118
with a stock 302 shortblock
stock aod transmision
stock suspension
mods were Novi supercharger, Edelbrock heads, Victor intake,50lb injectors,custom tune,3.73 gears, except for the gears I bought everything used on the Mustang forums,
figure $5000 max in mods to put a 4000+ brick in the 11s with mostly stock parts,
got 25mpg on the highway and lasted 100,000miles and 300 drag passes before i blew it up,
no way no how can you do that with a V6 sohc/5R55E combo without scattering a lot parts,not to mention because of the HUGE Mustang aftermarket parts are dirt cheap to make a monster 5.0 engine
I will mention the earlier 5.0s (pre 92) came with forged pistons stock while the Explorer V8s have the hyperpathetic pistons stock which are pretty useless with superchargers,
If I would have had a choice I would have never bought a V6 but with the sport I was stuck with it

Excellent, I love that spelling.
My first LSC was only about a 15.6 car with Edelbrock heads and intake. The Mark VII is a tough car to get to move. My current version has rarely been driven because of the dead paint. I finally had to rebuild the suspension and do tires, so it's road worthy again.
Anything with a 302 based engine is so much easier to do that other Ford engines.

cool, I had a red SE as well, had a cool two tone interior,got it for $500!
Later I threw coils on it and 2000 Cobra rims and a cowl hood on it, was a cool and cheap ride for while, both my SEs ran 15.7-16.0 bone stock, 15.1-15.3 with 3.73 gears all else stock
I agree on the engine, for hotrodding you cant beat a 302 because of the huge Mustang aftermarket

V8 drivetrain swap abandoned
I've abandoned my plan to replace my SOHC V6 drivetrain with the 5.0L V8 drivetrain for several reasons. I haven't found a suitable donor vehicle after looking for more than a year. It would involve two non-operational vehicles (my Sport and donor) for an extended period of time with potential confrontations with the neighborhood home owners association. V8 exhaust manifold improvements are expensive, of questionable availability, are more restrictive than optimum because of engine compartment space limitations, and complicate periodic maintenance (replacing spark plugs and wires). I have very limitied knowledge of the V8 but have gained considerable experience with the SOHC V6. I have two new sets of replacement timing chain cassettes and the OTC-6488 timing tool kit. The V8 takes up more engine compartment space than the V6 restricting some modifications/enhancements. The fuel economy of the V6 is better than the V8.
Since driving my Volvo 850 turbowagon I have gotten used to the acceleration when the boost kicks in. I would like to feel something comparable in my Sport. I will avoid future modifications to my vehicle that might complicate the possible incorporation of a centrifugal supercharger in a few years.
