If you do want to use the 93 frame I would suggest a 1961+ truck as then at least the tires will fit under the fenders and also don't have to deal with a small engine compartment and running boards.

"Budget" and frame swap do not go together. It will nickel and dime you. I know your frame well as my Dad has an identically equipped 91 F-250. The front frame section is 5 1/2" wider than the factory one. The rear is 3 1/2" wider.

Here's some estimated costs:
$400 - worth of steel and misc hardware. (I had at least $350 worth and didn't change body mounts)
$500 - custom radiator as the 93 one is wider than the 48-52 hood
$250 - aftermarket gauges as the old ones won't work with a diff VSS
$300 - aftermarket underfloor booster and master cylinder. No room on firewall with 7.3L diesel. Also will interfere with front driveshaft.
$75 - electrical wire and that is just patching the 93 harness
$150 - aftermarket steering shaft with joints to connect box to whatever column you choose.

$1675 is just for a barely functional vehicle and no repair of the existing body which most likely needs new glass, seat recovered, rust repair and paint. Just new weather stripping costs $350 for the cab.

 

well thanks for all the replys so i thing im going to scrap the idea of 7.3 what about a 12v cummins 4x4 manual ?? would that fit?

 

I can't imagine wanting to convert the F-2 to a 1. The F-2 is a great truck, good sized. If your'e going to want to drive it much you are going to want to do something about the very loooow gear ratios, but they all have this issue...slim

 

Nobody like that idea?

 

The problem you might have with the cummins is the length of the thing. Anything is possible though....all it takes is time and money
A buddy of mine stuffed a cummins in a 50 Chevy panel truck. I cant remember if he did a frame swap or used the original. I do know that he had to heavily modify the firewall. He didn't make it a 4x4 though.

At least with a 4x4 you have a little bit of leeway on the width of the thing. Since 4x4's typically have big wide tires the older trucks don't look too goofy if the tires stick out past the fenders.
