1946 Ford Truck Engines
Hi all,
Could anyone please tell me what is the newest engine I could place in my '46 Ford pickup without having to change the old double clutch gearbox to a newer synchronised one?
I currently have a flathead v8 in there, with the standard 4 speed double clutch box.
As the wiring is old, mechanical fuel pump giving hassles etc, could I for example replace it all with newer equipment and put a new engine in from the 1980's or 1990's...? Will these newer V8's be able to work with the double-clutch box?
Appreciate all your help.
From South Africa.

You can but the cost of adapters and the work it would take to put a newer engine in would far outweigh the cost of just repairing the flathead.
But if money doesn't matter, you can buy adapters, but you would have to drive very carefully, the newer engines put out lots more power than the old flathead and with a newer, more powerful engine you could easily break the old transmission.
Here is an adapter for a chevy engine to the old transmission. I don't know what other parts you will need, but this is a start.

Thanks a lot for the reply.
The problem is that the truck needs to be totally re-wired. The old guy I bought it from converted it from a 6volt engine to a 12 volt one, took the generator out and put an alternator in.
The wiring has gotten so degenerated, that it is shorting and losing power somewhere. This is causing my battery to wear out faster, and is hassling the alternator.
The fuel line is getting blocked up every now and then by particles that are lifting from the inside of the fuel tank i think, it being so old and that. Either that or the mechanical fuel pump is not working so well anymore, but I think it's coming from the tank.
The cost of putting '46 parts back in is what has made me think it might be more worthwhile putting a newer engine and box in, but the flathead is running ok itself.
Like you say, i should rather fix that, maybe get it reconditioned at the most, and then just clean out and replace the fuel line and replace the wiring system....
Any other thoughts or tips will be greatly appreciated.

I probably would go to the parts store and purchase a couple inexpensive clear enclosure fuel filters and put one in-line to see how much particulate your pulling from the tank. (You have a second one if it gets clogged.) Make sure your tank is at least 3/4 filled and drive it so the gas "sloshes around" inside the tank to knock of any additional particulates or rust.
If there is a lot of build-up in the fuel filter, you may have to pull the tank, clean it out and seal it internally. Someone else on the site can probably instruct and recommend some products to do this.
Good luck..

Hi. It's me again!
I have sent my truck in for re-wiring and some other repairs. I am doing a total re-wire. I'm replacing the old radiator hoses, replacing the old flexi fuel line too. I want to put on a new pump and in-line filter, but still keep the old pump and filter on for show - Is that goignt to complicate matters in terms of the new pump, filter and fuel line? They are going to pull the tank out, clean it up and such, as it hasn't been cleaned out in years and is likely to be full of rust and the metal fuel pipe is too probably.
The problem I face here in South Africa is availability of parts. The old pump's diaghram may be worn or the rod.
Another thing I want to do is get two separate exhaust pipes running.
