Don't bother with the frame/body swap, its not worth the money it would cost to do.
Keeping the cost low is a matter of knowing what you want to do, and what you need (specifically) to do it. No matter what, there are going to be unexpected expenses.
Motor mount adapter plates are the cheapest way to physically set it in there, and in many cases the tranny mounting is just a matter of redrilling some holes on the crossmember to adjust it. You can re use things like the radiator, power steering box, assuming they are in good shape.

Blazer tanks seem to be a cheap way to get a tank setup for fuel injection, and the 255lph generic pumps are popular. You'll need a supply and return line with that motor. Usually a combination of regular hard line (3/8 supply 5/16 return) and fuel injection rubber line will get you there pretty easily. Parts stores sell the quick disconnect fittings to get fuel to and from the rail.


Is the truck 2 or 4wd? If its 4wd I'd consider looking for a 2wd tranny because the tailshaft on the 4wd unit will cause problems.
