I know all of you will say why?

The answer to that is to get the 4.3 stroker power for desert racing without all the complications associated with a SOHC setup. Its going into a '94 so each would be challenging. The reason to not go V8 is to stay within the 4.5 liter V6 limitation of the classes.

There is one thread in search but it is old news and needs some updating to be with it.

 

this would be new to me, i have not seen it done, i think most figure if you are going through all the trouble why not a v8?

good luck though, would be neat to see done.

 

ive seen a couple 3.8SC swaps, but never a 4.2

 

3.8 & 4.2 and a little stroked for 4.3 total, around 360 HP on the stand.

And it won't be a challenging install really, using a C4 and all the crap is gone. The real info I need is what are the problems with setup, electronics, ect.....this is a '96 motor so no OBII worries but i am trying to make it as simple as possible before we start.

 

96 and newer LDV should all be OBDII. I thought the 4.2 was intro'd in the F-series and Econoline in 1997 anyway. Regardless, anything unnecessary can be turned off in software.

The 4.2L uses the same bellhousing pattern as a 5.0/5.8L and there is a huge knowledge base for Windsor V8 swaps. I'm sure there would be some detail differences but it should be a similar swap. Clearly, the shorter engine should have the advantage of fewer clearance issues up front compared to the 8's.

Using the PCM and engine harness from a F-series 4.2 manual should put you in good shape for the C4. The factory advertised flywheel HP on the 4.2 was about 205~210 IIRC, seems like you'd have to do some work to get 360.

 

About 2/3 of the supersix package. Also a bunch of basic stuff, every one of those little things that free up HP, electric water pump, fans, reduction pulley.........very light & strong valvetrain, lots of titanium parts we got from some nascar guys way cheap and machined to fit........porting & polishing to hell and back.........Not quite the kitchen sink but far enough away from it to stay reliable over a long race season with just freshening between races. A few guys are running them and claiming over 500hp on them, but both of those guys don't finish 1 out of 4 races they enter.......I say make the motor strong but stay in the reliable range, let the suspension win the race.

 

good luck, i drove a shop truck when i was younger that had that motor. got excellent mileage out of it.

please keep us updated on the build process. maybe oneday you'll be a pioneer for the rest of us that want to swap.

 

holy crap, you guys are literaly down the street from where i work at. i work at smeding performance on sunrise. if you need any help with the motor please feel free to let me know, we have a complete machine shop.
