4.9 to 5.0 swap questions?
 

I've got a '95 F150 with the 4.9 300, 5 speed manual, regular cab, 2wd short box. Runs pretty good but I really need something that can get out of its own way once in a while.:D So I'm thinking about doing a 302 swap. The torque of the 300 isn't really a factor as I rarely tow. And I know the 300 is very durable, but 1) I'm probably gonna keep it and rebuild it anyway just in case 2) I've got a couple of extra trucks at my disposal if it does break.

First question, will the 5 speed manual that's currently in my F150 with the 300 mount up directly to a 302 or do I need an adapter, different trans, ???

Second question, how tough would wiring be? I would use a carbaurated 302 so it wouldn't need any computers, but as for as keeping all the other stuff working on the truck. I've heard there is an "engine delete" program you can put on some F150's that keeps everything working just fine. Anyone know about that?

Thanx for any help!

First, the basics. You will need new frame mounts for the engine, radiator, accessory drive for the 302, 302 flywheel(the 300 is internally balanced and the 302 is external). The tranny will bolt right up. You have "high pressure" fuel pumps in your fuel tanks that provide 35 psi of fuel pressure. A carb only requires about 8 psi. That would have to be addressed. It will be a lot of work, but if you got the time, and know how, go for it.

There's more, but gotta get to work.

I can't help but think that a carb'd 302 will not get much farther out of its own way than what you got, unless it's built. You got a 302 that's been built? You're talking about a lot of work for pretty minor gains otherwise.

I'm with muddy...i had a 93' with the 300 standard. it didn't have much in the top end, say accelerating after you've hit 80 or 90, but around town and up to about 70 it was pretty good. i've got a 95 fi 302 now. it's got umph but imo not worth the swap with the difference in gas mileage. went from 16-18 with the 300 to about 12 or 13 with the 302.

I have a 92 f-150 4x4 that originally had a 300 6 in it and i replaced it with a 351 Windsor . If i were you i would use a fuel injected 302 . Its not that hard to do. All you need is the motor mount brackets out of the same truck with a v8 and a computer which plugs right in and a new radiator and exhaust . If you get the same style motor wiring harness it also plugs right in. My 351 made a huge difference compared to the 300 six. I wouldn't go carb ,to easy to keep it EFI.

Im in the process of doing the same thing as you. The carb'd 302 i put in mine has a little under 400 horse though. Im not sure how long my transmission is going to hold up but we'll find out. Other wise the wiring was a piece of cake. The only problem im having is that the hydraulic clutch isnt liking me to much. I have a brand new slave cylinder and reservoir etc...and I still have to stop and pump the clutch every once in a while just so it will keep up.

I would not advise the swap. There are so many things you have to modify. I swapped a 300 for a 302 once. i found that the bellhousing bolt pattern was the same, so I thought it would be simple. Wrong. All the issues listed above proved to be enough that I swore I would never do it again.
Buy a truck with a V8 if you want a V8.
If you decide that you are gonna do it anyway, at least get a V8 from a truck. Not a car. I found out after building a 302 from a Mustang GT that the motor mount castings on the block are different than a 302 truck motor.
The list of problems I dealt with are more than I want to type out here. if you want to PM me I will try to remember all the things I did to make this work.

I didnt have any trouble doing mine and my 302 came out of a 69' mustang. I didnt have any trouble puting the motor in. I put the motor/tranny in and had no problems. I did everything in about 2 and a half days at least 5 to 6 hours each day. the only problem i ran into was using the alternator out of the mustang(no volt regulator). I would suggest the swap. i would do it again any day of the week.

hey guys, new to the forum. please forgive me and point me in the right direction if this has been covered. i've tried to find some info and have a little but i keep finding threads on the opposite of what i have to do.

i have a 92 f150 2wd automatic single cab long bed with the 300 straight six. great truck, love it. I have acquired very cheaply a 93 f150 4x4 5 speed single cab long bed with no motor. it had a 302 in it. for my purposes a four wheel drive would suit me a whole lot better. what all is involved in swapping the 300 into the 302 truck?

i've heard you need to change the motor mounts and the perches on the frame, other than that i dont know. i'm not much of a mechanic but my buddy is pretty good and he has a garage with all his tools.

thanks in advance for all your input, James

Howdy and welcome to the basement. Since you have the donor truck, not that big of a deal actually to move the 300 mounts over to the 4x4 frame. Harness, hoses, radiator, exhaust will all move over as well. Your 300's E4OD computer will run the 300 with the five speed behind it, just will set all the codes for the non existent E4OD, or you can buy a 300 five speed computer for about 100 bucks. The puzzle piece you are missing is a 300 flywheel to go with the M5OD-R2, as your current 300 flexplate won't help. I'd try to source that from a junkyard.

Rock Auto has 4.9 flywheels for around 60 bucks.

thanks so much. those are exactly the words of wisdom i was looking for. only other question i have is, off the top of your head do you know if i'll need to get a 300 starter for a five speed. i had read somewhere that the automatic and 5 speed had different lengths or something like that. i believe one guy had said when he swapped his starter sounded like it didnt disengage. thanks again for your reply, James

The Rock Auto catalog lists different starters for automatics and manuals, so I would believe that they are different.

4.9 to 5.0
 

I have a 96 f150 with 4.9 inline 6 with a 5 speed manual. I was wondering what all I would need to swap a 5.0 from a 95 f150 into my 96. I already have the wiring harness, the computer, and the motor mounts for the 5.0.
