ok guys i know this is asked alot but i cant seem to find what i need to know. here is what i have i have an 83 f-100 2wd with a 4speed manual trans. i also have a running 1983 mustang gt 302 h.o. what parts am i going to need to put the 302 into the pickup.i known i need the radiator and the flywheel from the mustang. i know i need to get new motor mounts. i guess what i need to know is will the clutch from the 300 bolt to the 5.0 flywheel and can i use the 4 speed thats in the truck or will i need the 5 speed from the mustang. will i need the starter from the mustang or a hole new starter or will the one from the 300 work. as i said i know i have most of the parts needed just need to know what im missing. also please dont say keep the 300 the motor is shot its got a cracked head and the lower end needs a rebuild and the mustang is so rotted it cant be saved i am working on very little money to do this so im trying to take 2 vehicles that are dead and make one out of them.

 

You need more than new motor mounts. You need a set of 302/351W motor mount perches. You will have to cut the 300 perches off of your frame and install the small block perches.

The truck trans from the 300 would be a better bet than the Mustang trans, IMO.

 

yeah i want to stick with the 4speed from the truck just wasn't sure if it would work and thanks i didn't know i needed the perches as well

 

get the perches from they JY, 302/351 perches were all the same from '80 - '96. I dunno about cutting them off, mine had 3 bolts in them (1982 F100).

what ignition system was on the '83 mustang? if it was DSII then your 300 ignition module should work. so will the distributor.

you'll need a 302 truck engine wiring harness (also JY)

Not sure on the clutch/pressure plate setup

 

The starter from the 300 will work i just done a complete swap on a 86 from a 300 to a 302. The perches are just bolted to the frame with 3 bolts any 302 or 351 from 80 to 96 will work

 

This is true on the 300 6cyl motors. The V8 had rivets and bolts on the drivers side. They will need to be cut out. Also get a V8 radiator for the truck instead of the one from the Mustang. (I'm sure you can part out the Mustang and make some $ if it truly dead. I try not to send much tho the crusher.) Your looking at $150-$200 new. Or get one from a j/y. I feel the Mustang Radiator may not fit as good. I have seen the F-150 radiator in an 83 Mustang. Also make sure you change the power steering pump to the Mustangs. The Truck will be V belts while the Mustang is Serpentine. It can be done easily, just don't rush it and cut corners.

I have done the 4.9 to 5.8 swap. Also did the 3.8 to 5.0 to 5.8 swap in my Capri. Nice thing about them all is they are easy to do and will give you MANY years of service without trouble if you do it right. Good luck

 

something must have changed with the perches, mine had 3 bolts each in my truck and 3 bolts each in the '90 model f150 i pulled them out of...

 

You are going to need a oil pan for the 302. The one from the mustang I have heard will work, but you can't get to the front drain plug after you install it in the truck. The mustang pan is dual sump while the truck pan is rear sump. Have you thought about what you are going to do about a fuel pump, carb and intake manifold for the 302? You are also going to need the truck exhaust manifolds and the y-pipe for the exhaust.

 

im going to run straight pipes into glass packs off the stock manifolds on the mustang. ill have to measure to see what type of clearance i have but thats the least of my concerns. im not sure about the oil pan clearance ill have to check into that with mine being a 2wd i dont think im going to have the same issues as people with 4wd if so no big deal. fuel pump carb and intake im just going to leave the way it is same with the power steering pump the 302 is all intact in the mustang and runs the way it is.

 

y will i need the new wiring harness bot motors are carbarated nothing electric on the motor

 

Interesting, My 88 F250, 85 F150 (donor truck) and the 80 F100 have all had the drivers rivited. Not sure about the 86 that is Canada built.

 

Yes it does work, A friend has a Mustang motor in his 90'S Bronco 4x4. I would think if you drove the truck up on ramps most of the oil in the front sump would drain to the back. There is what maybe 3/4 of a quart in it or so.

I'm not sure if you would need a new harness... I would figure you would want to make sure the distributor was a match to the ignition in the truck. You could always pull a j/y dist, BUT make sure you use the gear off the Mustang on the new dist, That is if your engien is a roller. I think it was 85 when they went roller but don't quote me on that. I have been wrong. Here is info why... Ford Basics - Mustang & Fords Magazine

 

it looks like the ignition box from the mustang will plug into the truck im not positive but they look the same.

 

Sorry, I saw 5.0 and I had fuel injected engine in my mind. 2wd and 4wd both take the same rear sump oil pans though. I believe if it wasn't mentioned already, the truck six radiator is different than the v8 truck radiator. And of course you can probably rig anything to work, but it will be up to you how much custom fitting you are going to want to do. It sure is nice and a real time saver if everything just bolts in, and it will if you get the correct original truck parts.

 

no problem most people assume mustang 5.0 that its efi as far as the oil pan and rad go for now im going to have to make the ones from the mustang work. im on a very tight budget and i need this truck to get my around till i can get another car.
