I am putting a SBC into my 1949 1-ton, What is the best automatic transmission choice without having to modify the cab to accommodate it? Open to suggestions and recommendations?

What's the final intended purpose? Towing/hauling? Just a driver? In any case, you're probably going to have to do some modification to the transmission cover in the cab for clearance. For a diver, I would suggest the 700R4, very common, GM used them in trucks up to 3/4 ton, and they have a good overdrive rear.

Its just a driver. Im ok with modifying the trans cover, will I have to cut the cab to allow the clearance for lets say a 700R4?

I cut mine very little. A ½ inch arc at most, right at the opening.

It is much easier to massage the cab slightly (which can easily be returned to the original shape later if you want to), than to cut up the cross member to avoid cab interference.
What rear gear ratio are you using?

Ditto on that Jim. (TH350c) NO other mods to floor area.

I am looking at putting in a 14 bolt ff alxe 373 or 410 gears.
Right now i have the frame stripped and painted. so I am kind of working with a blank canvas. Engine, trans and rear-end have yet to be decided on. I am trying to game plan the entire power-train before i go buying components. I like the idea of not having to cut up the truck.

With a 3.73 or 4.10 gears, you will want a transmission with overdrive. 700R4 fits that bill. Find one with mechanical speedometer, and without the computer controls.

1984 was the first year for the 700R4. You don't want one of those. Look for a late 80's, early 90's version. Figure about '93 or so they started getting computer controls.

Thanks, Did you replace the stock steering column when you upgraded to the automatic? I also have questions about brake pedal placement as there will be no clutch. I have not gotten the master cylinder & booster combo yet.

On my build, I modified the stock column and hung the master on the firewall. For my transmission, I had no firewall modification and made my own trans cover to allow for the Lokar shifter.

Blind68, I used a '68 pickup column in my 52 panel. It gave me turn signals and is slim as it lets you keep the key in the original position. Works nice with my 700R4 since it was already an automatic column.

Did you have to make your linkage or did you use the original 68 Pickup linkage.

Bryan, Looks like you're a pretty particular person. Maybe even a perfectionist by the look of your work! You've done an excellent job on your truck so far. Great welding, a beautiful interior, the Harrison and Arvin heaters turned out super, and you're pretty handy with a paint gun by the looks of that red cab! I love to see 'em torn down and put back together right, just like you're doing. You're going to have a beautiful truck to drive when you're done with it. Thanks for sharing the pics in Photobucket, and we look forward to seeing new ones added regularly. Can't wait to see the finished product!!

Blind1968, I used the original column but I bought a Lokar kit that fastens to the column then the rod goes down to the shifting arm which is all part of the Lokar kit. Works great.
