ok this post will be long, but if you know how to bulild a good crawler, please read and help me if you can. The current situation: 1989 K5, dana 60, 14ff 5.13 locked, 700r4, np241, stock 350TBI with near 200,000 miles on it it crawls "ok" but i'm not that satisfied, i probably give it a like 6 or 7/ out of 10 from what i want, What i have to work with: 1973 GMC Jimmy, axles from 89, 500 caddy motor What i'd like to accomplish: i have gone through about 4 NP241 transfer cases some how with this setup. therefor i'd like to get away from them if possible, BUT i love low gears. i also need to keep it able to do 65 on the freeway as its my only vehicle for a little while. what i'm thinking new tranny - from bowtie or monster the beefed up 700r4 new t-case of some sort, maybe doubler or something, along with this i'd need new shafts so basically i'm asking how i'd go about getting the lowest gearing possible/best crawling abilitys for a budget of say 3500-4000 i'll also be rebuilding the 500, since i have never touched a motor before, i dont know how to make it make more power than stock. ALL HELP IS GOOD HELP, dont think "well its common since that this or that will make power"
