Ok so bare with me here... basically I need help on which truck to spend money on first. So the first truck is... My 1985 K10 daily driver with 4in lift and 33in tires. It has a rebuilt 4bolt 350, sm456, np208 and 10bolts with high gears... 3.08 I believe. In town I dont even use 3rd (assuming you say, LOW, 1, 2, 3) and on the freeway at 60mph in 3rd I'm barely even pulling 2000 rpm. My gearing seems way too high and not good for towing. So the most logical thing to me seems to be get some 3/4ton axles with some 4.10 gears. No problem right... so heres my delimia. At my local tire store I have credit limit there from my previous set of wheels and tires. I can purchase a new set of 16x10 8 lug wheels (same style I have in 15x10s) and some new tires, probably some 315s.... or!!! There is my 77 K20 with a 7in lift and bushwacker fender flares. It had 38x15.50x16.5 gumbo mudders when I got the truck two years ago, they were brand new and sold them. Now it has some very very worn 36x12.50x16.5 Goodyear Wranglers. I would like to take this truck to some local mud bogs this year and I would like a new set of boggers. I've found some 38.5x15x16.5 boggers that I know it will clear no problem. So I'm not sure if I could finally put 3/4ton axles and new wheel/tires on my 85 dd, or get some new boggers for my beater... ugh!!!!!!!!!!!
