76 cab on 74 frame?
I'm in the process of rebuilding a 1974 dually f350, the old cab is fairly rotten around the roof. I managed to get hold of a pretty good cab from a 1976 truck, I ntend using the 76 cab but keep my 74 fenders grille etc, is there gonna be any major hassles? I hope not cos I've already bought it 
cheers

Will bolt right on provide that the 76 truck was not a 4 wheel drive. This will present some body mount issues, but you simply have to re-drill the cab for the wider rear mounts. Save the rubber (actually plastic) covers that plug the body mount holes inside of the cab, and drill the new holes with a hole saw, and your new holes will look factory.
I just installed a 79 cab on a highboy, and it came out clean as can be. Looks factory from inside of te cab. Would never know, that the factory did not punch the holes.

cheers guys that's good news for sure. I assume things like the dash will either work as they are or swap back to the original parts as necassary? I know the 74 had the fuel tank in the cab and that the 76 doesn't but thats not really a problem as I can easily mount a tank along the frame rail.
another thing I'm a little unsure of, it's got a 360 in it and I want to replace the mechanical fuel pump with an electric one. what kinda gal/hour will it require as new pumps all seam to be graded this way. I hope to get 15mpg so at UK speed limit of 70mph I see it using no more than 5gals/hour but will that be enough?

5 gals per hour????? Your truck is gonna require far more fuel than this, and this 5GP/Hr pump will be far too small to meet the demands of a V8 engine. I mean, if you are using the most efficient scenario such as highway speeds, using high gears, and never consider pressure, or consumption dirung acceleration, or higher rpm requirements, then you will fall short when the demand is higher.
As an example, and just an example, higher volume pumps that can maintain just over 12 psi will deliver over 100 Gp/Hr. Your engine may never require this much fuel, but during higher demands, you will have adequate volume, and never loose pressure. These same pumps under load will prodeuce around 70 Gp/Hr at about 9 psi. This represents a loaded condition, and this volume should be mroe than adequate.
You may check out the forums that are specific to the Fe engine, or even the specific forum for your question, but I do believe that 5gph is not enough volume, nor will it provide enough pressure.
