Manual trans swap from I6 300 to V8 302 possible?
I have a 92' Ford F150, Ext. cab, long box, it has the 302 5.0L engine, i'm looking for a compatible 5 speed manual transmission, however i'm only finding inline 6 trucks with the 5 speed, will this work? (I had an E4OD transmission in my truck, the manual will solve a lot of tranny problems and help with MPG plus HP and torque.) Also i've gone back to the good with a carb and no sensors or computers, so and codes thrown is not an issue.
- I have heard that I need an imbalanced flywheel, but I can't find any info this either.
- Thanks ahead of time for any information!

Great! Sounds easier than i thought. How about the cross member? I stopped and looked at a couple parts trucks for sale but none of them were like mine, (The trans cross member bolts to the frame on one side but has a round hinge like mount on the other side, like what would be on a ranger.) I had the E4OD in it. Will the trans cross member from a '92 F150 manual I6 bolt up to a '92 F150 E4OD 302?
If not, how much work am i looking at here? I don't mind welding but i haven't owned a decent one for a few years now. Would it be as easy as drilling new mount holes and bolting it up?
Thanks again! I never expected such fast and thorough replies!

Thanks for the corrections on the imbalance size, I wasn't sure one way or the other but I knew if I was wrong someone would be along shortly to correct me.
You will need a crossmember specific to your transmission. No welding needed. I would be surprised if the holes weren't already there, but if they aren't, a drill will fix that very quickly.

Any 5-speed crossmember from '88 through '96/'97HD should work. I put a 5-speed crossmember from a 1995 F150 in my '87 F150 (no drilling required), and it mates with the '91 F250 ZF transmission I have using a '95 F250 manual transmission mount. I'm not sure if you have a 4x2 or 4x4 truck, but the crossmembers are different between the two, so make sure you get one that matches your truck's configuration.

I have a question along these lines, if someone would like to help.
I'm planning on dropping the 4-spd out of my 5.0 equipped '90 and replacing it with a 5-spd out of a Spr Cab 4.9 equipped '91. Do I also need the crossmember out of the '91 to go into my '90? Also, I'm guessing I can reuse my current 5.0 flywheel. I was planning on replacing the clutch assy and slave cylinder while the transmissions were out. Any thoughts?

You will most likely need the crossmember from the 5-speed truck. The 302 clutch and flywheel will work fine with the 5-speed. I recommend getting a new OEM slave cylinder (available at a local dealer or online through one of the site sponsors) to install along with the transmission. You will also need a new clutch hydraulic line if the 4-speed used an external slave cylinder.

4.5 years later.....yes....same answer. The problem is going to be the computer in the truck now is expecting to be connected to an electronic controlled E4OD. With that missing the Check Engine Light is going to glowing all the time the truck is running.
If you do not want to see that you will need to source a computer (PCM) from a manual or AOD equipped truck.
Question to you: Are you sure you have an E4OD behind that 5.0L engine? Most 5.0L equipped trucks of this vintage have a mechanical/hydraulic AOD transmission.

What other's in this old thread have failed to mention, is the starter motor will need changing as the manual is diffrent from the automatics.
