1998 exploroer 5.0
I want to put the motor and trans in my 89 F150 4x4 and keep the efi if at all possible..
What transfer would I need to get rid of the full time 4x4?
and what about the ecm would that be a problem if I changed the transfer?
How would you guys do it??
I'm thinking if it's going to be a pain with the ecm I would just run an rpm intake and a 600vs holley I have along with an HO cam and 1.7 rockers..
Lose the automatic for the 5spd I already have in the truck, I have the flywheel I need...
I found some cheep shorty headers for the gt40P heads 150.00 so I might get those...
Thanks Steve.....

You're giving up too easily, that motor will run with the stock '89 truck computer and engine wiring, and you can swap over the '89 truck intake and distributor(with a steel drive gear mounted) to make it a no brainer drop in. And yes it'll make lots more HP and TQ than the stock '89 5.0, and get the 5-speed anyway.

The truck was a factory 4.9 4spd 2wd, I put the 5spd and a 78 bronco front end.. kept the 8.8 for the speed sensor instead of using the 9" out of the Bronco.

The 5.0 truck intake is better(flows more) than an unported Explorer intake, there are sharp kinks in the ports in the lower portion of the GT40/Explorer intake(typical of most Ford EFI intakes actually) while the truck lower has very gradual bends. Apparently the Explorer flows about 180cfm per runner on average stock while the truck manages close to 200cfm, and it only needs some minor work on the lower exits to open them up to achieve 240-250cfm per runner while you have to straighten out the kinks in the runners on the Explorer/GT40 by welding and then re-radiusing the bends to achieve those flow levels. Here's one of my favorite pics of the 5.0 truck lower, there aren't any other Ford lowers that you can see straight through all 4 ports simultaneously like this..
The truck intake also has quite a bit more throttlebody on it, dual 51mm versus a single 65mm. There isn't much difference in total port length between these intakes either, they're all within an inch of one another so you won't see much impact on upper rpm HP potential.

Kind of info I like... looking for a 89 5.0 truck, would it have to be a 5spd 4x4 truck and it's SD right so cam choses will be limited right..

Unless you've already got an HO cam, use the Explorer cam, there's only a few degrees difference in duration and .030 lift on the intake side between the two cams. Setup the way you listed it(carb), it'll run exactly like it's an EFI motor. I had one just like it in my 89 Ranger. Cold starts with no choke and not touching the go pedal to prime it, down to 25*F. Pulls from idle to 6000, a pure pleasure to drive with a manual transmission.

Just as an afterthought.........Holley used the truck lower intake with their EFI uppers. I think someone else did too.

I got a guy that says he has an HO cam said he came up with .280 lobe lift on the cam.. is this an HO cam or just a plane Jane roller????
.280x1.6= .448 valve lift
x1.7= .478 valve lift
is this a ho cam??
.280x1.6= .448 valve lift
x1.7= .478 valve lift
is this a ho cam??

Yeah that's The HO cam, it produces about 0.444" lift and 266 deg durationon on both intake and exhaust while the Explorer cam is 0.422" and 256 deg duration on the intake side, exhaust is the same as the HO. The plain jane cams are much smaller than either of these. If you do use a HO cam it's often recommended to advance it 2-4deg to get a little better low end, and you could add 1.7 rockers to get a little more area under the curve. Stock springs will handle this too.

All truck EFI 5.0's are exactly the same so it won't matter for thse parts, and SD does limit cam choices but there are several that will work including the HO and Explorer cam, and aftermarket cams with 114 LSA and less than about 210deg intake duration at 0.050".

Like I said this is up in the air right now... Thank for all the help I'm old school, so not so good on the performance efi... was ASE certified back in the 90's... lot of things have changed ... I might try and trade the motor trans for a big block 5 spd 4x4 transmission so I can run the 400 I got waiting.. 71 2V Cleveland heads Ported, SS Valves 9.5 to 1 compression, Still waiting on the cam and intake.. I want to spin it to 6000... I built one not long ago that pulls like a freight train to 5200 and thats it.. stays right there.. Just kicking around Ideas..

Ya the more I think about it the more I want the 400... the last one I built really surprised me even with the 204 214 cam it would rip to 5500 or so had a bunch of torque... got to love that 4" stroke...
