Hey guys well i have the option to pick up a very clean 89 SC with a rebuilt 5 speed, but no engine. Anyone have any feedback on what else can be shoehorned in that baby to get it rolling again? Obviously another 3.8 SC engine, but any thoughts on something else, 4.6, 5.0 , or thoughts on the cheapest route to go? Just looking to possibly make it a screw around track car for a couple guys, split costs.

I'm no expert but without changing transmissions you're looking at a 3.8SC or 302/351 if you're going to strip the electrics and go track only. 4.6 bell housing pattern is different.

Even with the 3.8SC, the cam is different depending on if it was destined for an automatic or 5-speed. Just something to keep in mind...

At least that's what I recall hearing in one of these dry boring Ford tech videos.

The are some years/tranny options that had different grinds, but not enough to worry about.


You can swap in a 302/351 block or as several have done, 460 based block.

Yeah, the 89 Manual had a slightly more agressive cam .. all the rest should be the same for both autos and manuals.

I checked those cam specs. Comical to say more aggresive.

A 5.0 would be a fun choice. However the SC is fun too and it's ready for the 3.8 now.

Not completely true. The first two years of Grand Marquis and Crown Victoria's had a block with the 5.0/3.8 bellhousing pattern. The block is Iron though, but is not a bad thing, still weighs about the same as the 5.0. And they came with an AOD (reason why the used the bolt pattern probably.)

a 5.0 would be cool, and you can buy a painless wiring harness to wire it all for FI. Or you could also swap in a 4.3L turbo, or a built supercoupe engine, or an older iron 4.6 with PI heads, cams, and intake, there are many options.

Just in case you haven't made up your mind yet...

After having to tear into a SC 3.8 that I'm parting out...go with a 5.0

Not saying the SC 3.8 isn't a good engine, but in my limited experience it's a PITA to work on, even doing basic things like changing spark plugs is a chore.

The 3.8 GN is a different animal from a n/a v6
