Hey guys need your input here...

I am putting a 254 with a T98 on an F2 frame however all the holes line up but 1... I find this odd cause I figure it should be a bolt-on swap (I am probably wrong) If I do line up the transmission bolts the engine will sit at an angle...Theres a lot of knowledge on here so maybe someone can chime in!

 

That is odd!. I would think it would fit just fine as far as lining up mounting bolt holes also.
Seems like member Scotty's 52 f3. Ford Truck Enthusiasts Forums - View Profile: Scotty's 52 F3
Was going to or did put a t98 in his truck.
I thought it bolted up but he ran into a different issue with clearance somewhere.
Im interested in this as well as ive slated a t98 for my f2 as well. I wouldnt think it would matter wether its a 254 or the 239 either.
Are the front mounts tweaked on the frame or on the engine wrong somehow. Does The 6 cylinder have two lefts or two right side mounts or something like that bolted on? Im not even sure if thats possible?

 

Check the rear foot on the T98 transmission. They are prone to breaking, It may be cracked and bent back. I had to weld mine. It should be a bolt in fit. The rear foot on an F4-F6 T98 transmission is about 5/16" taller than one for a F2-F3, but it shouldn't be a problem.

I pulled it out of 1950 F6 and it sat in there like a glove. However; I just checked it and appears the passenger mount is bent forward but not cracked, I cleaned all the grease off. Are these forged or castings? If it's forged I think I might be able to heat it up and bend it and let it air cool at its own pace.

 

They are cast iron, so if it bent it is probably cracked.

Well shoot that puts a major halt to my project... Thanks guys for the input though.

 

I have issues with the trans sitting higher and the trans cover not fitting. I did have to loosen the engine mounts to get it all to line up easier.

I plan on modifying or grinding the rear mount to let the trans sit a little lower in the rear.

 

Good info. Im going to need to do something as well then. But maybe ill wait for your results first!
The other issue i would have is my f2 Marmon Herrington has the double cardon ujoint right behind the trans about 4- 5inches or so in length before mating up with the transfer case. So i definitly dont want to mess with all that mounting locations, unless having a bit more deflection in the joint wont cause any problems? Im a ways away from mock up stage though so ive got time.

 

Hope this helps.

 

Thanks Scotty for the pictures. I will have to see how she sits when I put the cab down this weekend. I did notice my pulley hits the crossmember. Maybe my engine sits too low up front..

 

That's another thing. The rear sitting higher made my fan hit the shroud at the bottom. I put in new front mounts and had to tighten the belt to get more room.

Sometimes it the little stuff that gets ya.

Mine is fine for now. I will address the mount and floor clearance when I get closer to body work and the cab comes off.

 

So if you had to weld yours up do you think one could be cut and shortened the 3/4" and re-welded?

 

I don't know why it couldn't be done. I think it is between 5/16" and 3/8" difference between the F2-3 and F4-6 mounts. Ironically I had to shim my transmission up as my transmission must be from a F2 or F3.

I figure if I put new mounts on it should help the old ones are worn bad. I will be really curious to see how the engine sits though this weekend...if I can get my bracket fixed. I may be welding it..

 

I'm curious about the different height T-98 rear mount / rear bearing retainer. When I dug through the 48-56 Ford Truck Parts Catalog it only had one part number for the 48-52 part. I'm guessing that the difference is simply loose tolerances on the parts when manufactured. These transmissions were only offered in F-4, F-5, and F-6 trucks when new and they all use the same transmission cross member. Thoughts?
