10R140

I'm doing a restomod on a 1949 Ford F2. I'm planning to install a 7.3L Godzilla engine, and I want to mate it to a 10R140 transmission. Anyone try to stuff the 10R140 into one of these trucks? I'm wondering how much of the floor pan will have to trimmed away to get it to fit.

Man, that sounds like a really fun project. You're also probably in uncharted territory for this forum. Please consider doing a build thread here and document your adventure. I'd love to follow it, and you could be the help someone else needs in the future.

I have the 7.3 with 10 speed in my 2022 superduty. It will make a wonderful power plant for an old truck!

Yep

The sheet metal is all smoothed out and primered. I'm painting the truck to match my 1995 Harley Fat Boy. I had a local shop here in San Diego build me a DANA 60 rear end that came out of a 2016 Ford E350. I'm putting a fuel injection ready gas tank in the rear of the frame. I'm retrofitting the front drop axle with rack and pinion steering and beefy disc brakes. I just got the bench seat back from the upholsterer.
Original seat frame and springs.

you are correct but I'll tell you these 7.3 engines will rev and the hp/torque is smooth and steady nearly 450hp stock. These motors pull extremely hard and sound fantastic!

they sound fantastic because ford went back to the y block firing order!

Yep, it's not a cheap venture. Jegs recently increased the price of the crate engine by $1400. $8750 for the crate engine, $2470 for the engine/transmission control pack, $1150 for the FEAD kit with A/c add on, $8000 for the transmission assembly, $4640 for the retrofitted DANA 60. It would have been cheaper to just go out and buy a new truck, but where's the fun in that! I built the engine for my 1967 convertible Firebird. That Pontiac 400 cost me over $12,000 by the time I was done. It does put out over 600 Hp at the wheels though, and is nearly bullet proof.

In 1970 if you wanted to build a '32 ford with a "modern" drivetrain, that'd cost you about $2500 in todays money.

No wonder why the young people of today are hardly making any economical progress.

I drove by a fairly middle-upper-middle class neighborhood and there was this house that had just been bought. Sitting in the driveway was a fairly new Ford F250 diesel(fancy version), and next to that a 1-2 year old escalade.
On the street was another fancy diesel F250.
I'm sitting here looking at a "middle class" neighborhood with "normal" people and they have darn near $280k worth of CARS in front of their house.

I'm not saying you're building your truck wrong, I'm just saying it's ridiculous that your Trans should cost $8k. Your engine shouldn't be $5k unless its new off an assembly line with warranty. Some wires an a computer should be $400


Way too hard to "build something nice" today. Way to hard to build wealth today. If you don't have successful parents to give you stuff when they die, you're just gonna suffer because your average youth today ain't gonna be able to DIY.

Just having an old engine rebuilt costs a fortune nowadays.

I bought my low mileage Coyote out of a wreck. I saved a lot of money.

I looked for a used 10R140 through Car-Parts.com, but could not find one for my application (7.3L gas, 2 wheel drive, no PTO). Most of the shops out there are selling the 10R140 for the 6.7L diesel engine. So my only choice was to get a new one. Here in California where someone can work their first job at McDonalds starting at $20/hr, you can bet that machine shops are not cheap. Labor rates run upwards of $199/hr.
