As Charlie says, although the top comes off that tranny its not a toploader if it came in a 2 ton truck, it would be the T98 which was used in trucks from F100 thru F 700 and it is a truck transmission that you do not want to go pulling out front of traffic with, double clutching is neccesary sometimes with them and first gear is rarely used unless you are on a farm bailing hay, then you could put it in first and get out of the vehicle and let it drive itself while you loaded hay on the back, its that low. Then some big trucks came with the Clark 5 speed which even had a lower granny gear.

For a street/strip vehicle, you do not want a truck 4 speed.  It is unnecessarily heavy and bulky, is not even remotely a performance transmission and you won't be hauling anything with your proposed combo so the additional ability to do so will not be used.
The most cost effective manual option for you is a 3 speed.  Which 3 speed will depend on how you choose to mount  your engine. Cars or trucks do it different ways.  One or the other may work better for you and which 3 speed depends on the bellhousing you choose.  Truck 3 speeds have a longer input shaft with different spline dimensions (among other things) than a car so bellhousings are a different depth and the transmissions are not interchangeable between the two.

The toploader 4 speed did not come in any Y block vehicle.  It's probably just a truck 4 speed.  The top does come off but it is not what is known as the toploader.  You do not want that transmission.  Now, if for some reason it is an actual toploader, that could be worth getting.

Cool handiwork!!! Good engineering there! Where do the T-98s come from and what bell do you run? I like the idea of a manual for this old ride for the nostalgic value. I am usually an automatic guy, but this is a little different. I have a friend that has an entire 292 and top loader 4 speed, but it's from a 2 ton truck and would be a little heavy I think. Would the bell even be the same on something that big or would it be the large round bolt pattern? Trying not to spend much just getting it on the road, then I can work on it as we go. Later in it's life I could see a supercharger on top!...(devilish grin)...or twin turdblows..
Also as it turns out, my little pickup is a 32 not a 34 like I was told. Even cooler!

I have a T98, aint the best shifting with straight cut gears but I use it for work, load it with wood, handles great with the helper springs. This is the only factory half ton frame I have seen with factory helper springs. Notice the exhaust I made hook on with srings like snowmobile exhaust pipes. I can just unhook the springs and one wing nut after the muffler on the hanger and can drop the muffler off for open headers.

Nice fit too from the look of it! I was thinking a Ranger or Exploder frame possibly. I like the idea of the twin I-beam because it looks like the original somewhat. I want a lower and lighter ride for mine than a 1/2 ton frame. That's a cool flatty! What transmission are you running???

! used a 72 F150 with helper springs for my Rat Bed! Drives like a dream!

Now to decide what frame to mount this baby on. Decisions decisions...

I just went to the salvage yard to talk to my old friend Bruce and ended up procuring a 1934 Ford Pickup cab, doors, Knox bed and hood. Straight and still has the visor!... Looks like I know where my Y-block is going!!! WOO HOO!!!
