I searched.. but maybe im using the wrong search strings. Has anyone swapped a 3.8SC motor into a fox body mustang? If so, can anyone point me in the right direction?

I don't recall ever seeing one into a foxbody. But there is a guy at the sccoa that has done the 3.8sc into a sn95 style. Last time I checked around over there someone was throwin a supra motor into a supercoupe which was an interesting swap.

hmm

Hm thanks. Still considering the swap, but sometimes these things end up costing more money and netting less HP than just going with a 347

that's a pretty stupid choice, the 3.8L motor is a horrible engine. Sorry to the v6 folk, my opinion comes from experience.

Yea i respect your opinion. I have had experience with the motors myself and they are a pain, but they are very torque and cheap to come by

Are they any lighter? You would think it would be entertainable considering the supra's are 3.0 liters and turbo'd and blowing away mustangs left and right. I seriously don't get it.

Why not just rip the Eaton M90 off the v6 and throw it on the 5.0 like this guy

This guy came to my work and had a Super Coupe motor in a 96. It was jammed in there with a spoon, had no room to work at all. He had to have all custom piping made from PVC. It looked like hack work to me, but it was interesting and cool. He said it moves pretty good too. He said it took a lot of time and $$$$

sorry about the harsh comments, I was drinking last night.

my hate for the 3.8L motors comes from the head gasket issues.....I've been through several cars that all blew, and fixable or not, I'll never touch that motor again.

Lol, v8 dont worry about it man. Well i was hoping that it would be easier to work on the sc motor if it were in a fox mustang.. but i guess with all the piping it would be a monster.

It would be a hell of a lot less headache, and you would be much better off sticking with a windsor based motor. You said the 3.8 was torquey, a 347 will have a helluva lot more torque than a 3.8 with less headache, and aftermarket parts are dirt ass cheap for a windsor.

It's just not a practical swap. It'll end up costing you more money than a budget built 302 and net less HP. If fuel economy is your issue then build (or rebuild) a 302 with that in mind.

I had once, considered putting one of those 3.8s onto a tractor mower. I never got around to starting that project though.

Yea the more i look into it, the more i realize that i am better off sticking with 8 cylinders

I am not too worried about mileage as i dont drive it that often.

I don't see any way possible for a 3.8sc motor easier to work on than your standard 5.0. I've owned an sc myself hated working on it every minute a simple plug change is a monster on those, along with valve cover gaskets. You gotta take half the motor apart just to get it done. None the less it would be a cool swap to be done though not sure if the sc motor weighs less than a 302 but it may come in use for autocross if it were too.

You could always find an '86 or older Mustang with a 3.8 v6 and adapt the blower and all to it.
