1944 Jeep Willys drive train swap help

I found my familys old 44 jeep and the 2.5ltr-or whatever 4 cylinder was in it- is seized and the 3 spedd tranny only goes to 60mph and at high rpm's. I have to put a new engine in it, and also what can I do about the transmision, i want to drive it alot, so could I put in a 5 speed or something?

Putting a chevy v8 small block, probably 350 or 305 in it. keeping the 3 speed so i can keep 4x4 without braking the bank on new parts. All i need is the engine, tires, grille, windshield, and radiator, and eventually a roll cage so I can put a cab on it.

I'd recommend a V6-either a Chevy 4.3 or a Buick 225/231. Plenty of power for a small Jeep and easier on the drivetrain. If you want more top speed, you either need to go to higher diff gears (which will hurt you off road)or get a Warn/Saturn overdrive unit for the stock transfer case (expensive but worth it).

Pinto 4 cylinder and a T15 trans plus the overdrive.

Chabge of plans. Restoring a 1964 jeep willys instead. it has more of the parts I need and ran 5 years ago as a plow truck. Also might have a ford 302 truck as a donor engine and possibly trans. The jeep still only has a 3 or 4 speed with a buick v6, what could i use to put the ford motor in the standard tranny? not talking motor mounts but like what I need to put it right on the tranny. How hard is it to put a auto tranny from the ford in it or a 5 speed?

Before you go off half cocked, I would drive the V6 for a while. It is by far the best engine offered in a CJ. That being said, you seem to be in a big hurry to start a swap on something. I've found that it is best to drive the rig for a while, evaluate it's performance, then formulate a build plan that focuses on the overcoming/fixing the deficiencies you find.

Sorry for the confusion but thats what i was going to do. With a closer inspection the whole body needs replacing and Im probly going to do a fiberglass body for its non rusting. as of now the floorboards are gone in the left side and alnost gone on the right. After the engine is running and everything works we are going to strip and repaint everything then put the new body on and roll cage and new soft top. it also needs new seats.

Update again. Wordpress going up this week, I will put a link up when done. I un buried it from all the old tractor parts on it, in it and around it. Found the original radiator and grille in the back of it. Thats a huge lifesaver. Hopefully tomorow I will get around to pumping up the tires and get it dragged out onto a trailer to bring to my barn where i can clean it and see what I need to get it running. If the flathead f head 4cyl doesnt run and cant run without major modification ( if it doesnt run then I can get the carb from sticking out the hood so i can put the windshield down) what engines can o put in it? Im not looking to climb a wall or go fast. I need it to be small enough to fit in without major complication and easily mount to the t 90 tranny.
