hey i have a 1977 chev half ton with the 4 speed (i believe its the sm465) and as you all no it has the bull low first gear which makes first mostly useless as i dont do alot of towing so i was wondering if there was a regear kit i could get or something like to make the gearing so its more like a conventional standard thanks for your time
the trucks get stuck with 1940s manual transmission technology until the 6 speeds came out in the 2000+
the nv4500 5 speed they used had the same gearing for the first 4 gears but they stuck an overdrive on the back of it.
that is why so many people want autos in trucks

well the fourth gear is still one to one and the second is the same as a close ration fourspeed first so just use the truck as a three speed. when you need the low gear it is worth its weight in gold.
you could always go with a newer 5 speed or if you have to have a four speed you could get a splitter to effectively make it an 8 speed. lots of options .

put on big enough tires without regearing the diffs and you can use 1st all the time lol
