[dman1982]

i havnt posted in a while, been super busy with work and my truck hasnt broke on me, sunday i had to replace the universal joints (again!!)...my truck is a 84 k10 with 4-6 inches of lift...i put 4-6 because im not really sure which one it is im pretty sure they sent me a 6 but i ordered a 4, anyhow, i go through u-joints pretty often, I've 3 or 4 of them in 3 years time, not too bad i dont think at 8 bucks a piece or so, kinda getting off track here a bit, but with my lift im running 35's and got a th350 trans with a older 350 (about 150-250 thousand miles, not sure how many times its flipped but the previous owner said it was original) its pretty tired any how but running good, this thing is a slug, but i like it, someday i want to put a 700 in it due to mileage, but for the mean time im looking to swap gears, looking into 410's i just drive back and fourth to work, but like to play as well, just looking for some advice, ive had this truck for a few years and enjoy it, im just poking the bush really
