To the best of my knowledge, there is a company that makes a manifold for the SPI heads. It is not for an Eaton though. It is a swap for the 3.8 moostangs with an autorotor. Sorry, I dont recall the name.

I'm not sure, but I don't think the bottom end would hold up to that supercharger very long. It was never made to handle it, so it would be like putting it on a 3.8NA motor. You would blow it up pretty quick. But as far as bolting everything on, it will bolt right in place of the intake you have right now. Then you just need to deal with locating the intercooler and plumbing everything, but it would work if you build a real strong bottom end first.

well, the bottem might hold up. Someone has the supercoupe supercharger in a 95 mustang. The engine hasnt died yet.

You'd have better luck putting on a vortech though. You can find used 3.8 ones pretty cheap (around 1500 or so for the whole setup)

The first issue is, how do you plan to get the 4.2 into the Ranger? That truck never came with a 90 degree V6 like the 3.8 or 4.2. They always had the 2.8, 2.9, or 4.0 V6, which are all of the same 60 degree V6 engine family.

No parts are interchangeable between a 4.0 and 4.2.

They will fit...I had a 289 in my 83. Also. as far as strength, it MIGHT work. There was a guy on some mustang site that had a 4.2 with some good boost running 10s. But it was not a box blower, it was a centrifugal. I would check with some of the 6er mustang sites.

FastEDN: I have a 90' Ranger with a 5.0L V8 in it.. so the 4.2L will bolt in and I might add much easier.

The 3.8/4.2 share almost the same dimensions as the 5.0L and in a ranger its actually easier with the 4.2 as it leaves more room upfront for a fan and bigger radiator.

Wouldnt his best bet be running the S/C heads on the 4.2L engine??? this way the blower bolts right on.. if he wants to spend the money then he cant have the heads ported and maybe order some better pistons for the 4.2L to lower the compression ratio down to possibly 8.5-9.0 which is more suited for a blower engine.

I should have been more clear. I wasn't implying that the 4.2 would not fit in the Ranger, I was trying to make sure that the original poster wasn't under the impression that a 4.2 would bolt in place of a 4.0L, if that is indeed what resides in the truck now.

A 4.2 could certainly be installed, but some custom fabbing would be required. There are kits available to install a V8 in a Ranger, even ones for doing a 460 swap. But I'm not aware of any to install an Essex V6.

Im sorry about that Ed...I was not trying to go against you. I was simply stating that it could be done easily.

add to my original post

i have a 3.o now i have all the info on putting a 3.8 in there its not all that uncommon to do mainly b/c there is more upgrades for it... i am using this truck for a drive and road race purposes so i didnt want to put a heavy v8 in there and besides that the truck is lowerd 5 inches in the front and 5.5 in the back so anything as heavy as a 302 i would be drign the oil pan everywere. i just wasnt shure if the manifolds would bolt up. and if the sc heads would be a better choice im haveing the egin machined and im upgraiding the rods and piston im going to have the bottom end build to handle the supercharger i cand wait to get started on this its going to be a verry sic truck

Prob like the 2.3T swap, using the wiring harness from a donor car would be the easier way of doing it.

No apology needed Chris, you were stating facts correctly. :)

A 4.2 with a Super Coupe blower setup installed isn't going to be much lighter (if at all) than a 5.0L engine, so you may want to reconsider your options. A 5.0L can be bolted in using a kit from Advance Adapters or Total Performance. It would be a lot easier to get good performance out of it, and you wouldn't have to worry about the potential for failure of the 4.2 engine, being stressed with a blower that it wasn't designed for.

But hey, it's your truck. A 4.2 with a blower in a Ranger would be very neat to see.

I have a SC and had a v8 Ranger. I would reconsider the swap. In fact, if I had the choice, I would setback the engine and run an auto this time. I think you would like the overall cost and ease of already having the kits available.

The biggest Issue I see is that the 3.8/4.2L engines are WIDER than a 351W though I have seen a few 3.8L rangers before, even a Pre-runner with a 3.8SC engine. You can use any 3.8L block for a 4.2L buildup and a NEW 4.2L crank from ford is only 239$ (picked mine up this morning) and you need to use the 4.2L oil pan if it fits your chassis or one from a 01+ 3.8L mustang to clear the crank.
