Your gonna need a dual sump oil pan, oil filter relocation kit, motor mounts and then all the little extra odds and ends that follow doing these swaps. Its not as easy as just pulling the stock motor out and installing the 302. You could make the C-4 work, but your gonna have to either get a adapter for the stock Transfer case or try and find a Dana 20 out of a early Bronco or F-100 (if you go with the 20 make sure it is the 4hi/4lo version. They also came with just 2wd hi and 4wd hi). For the 20 you would also need the tail adapter for the C-4. You also gonna have to make/find a cross member for the T-case (I used a early Bronco cross member that I modified to work).
As far as the pedals go, just use what you have. My Ranger was a 4spd and I just wired the clutch pedal down on the floor (its out of the way and I never notice it).
I use the in tank fuel pump (my tank is out of a 87/88 Ranger, so its the low pressure electric) and I run a pressure regulator (Mr. Gasket, adjustable). I got all new sending units and the stock gauges all work correctly.
I used a B&M mega Truck shifter in mine.
I had custom drive shafts made Dana 20 on one end and Dana35/8.8 on the respected other, that are correct lengths.
Like 85 said, a 302 swap is not the place to try and skrimp by. Do them right and it will work, cut corners and your gonna have a giant pile of no good parts.
