4x4 low only?
Ok all you gear heads I just picked up a strong running 74 f100 with a np435 tranny 4 speed and a dana 21 transfer case but I only have 2 wheel drive and four low is this comon in 74's if so is there a diffrent transfer case I can replace it with to get four high with out too much work on the drive lines?

Last two posts are correct as far difference between Dana20 and Dana21. I would think it would be a Dana20 "J" shift by 1976 but that doesn't mean much. Stuff gets swapped. Make sure hubs are unlocked and get the shifter moving. You'll find out what you have. If you have side to side movement, it's a "J" shift. I can post some pic's if you don't figure it out.

no 4x4 high
ok guys thanks for the helps so far but this it what I have a DANA 21 transfer case this is on the tag on the t case on the handle of the t case it says 2 wheel forward and 4x4 back there is no 4 low or 4 high but when you put it in gear it acks like for low in just creeping and this is in second gear? so is there a diffren tcase that will give me 4 high with speeds up to 40 mph or am i stuck with a slow 4x4?

Actually looking for the gear ratio of front and rear axle. With 4:11 gears you would be turning 2650 rpm at 55mph. 4:56 gears, 2850rpm. Second gear is still pretty low with a 3:31 ratio.
