    Cutting out/dying while driving

    My 1978 K20 just started hesitating a lot and often dying when driving uphill when I have to hold the throttle, even less than half open for more than 10 seconds. 350 engine with brand new Holley carb. Little Edelbrock red fuel pump and a fuel filter with a return line. The filter and pump were...

    3 inch rake after tuff country 4 inch lift.

    Recently installed a 4" Tuff Country lift on my 1978 chevy K20 and there's about a 3" rake now. Here are the fenderwell height differences before and after lifting: Driver front: +3".

    Rear wheel drive with NP-203?

    1978 Chevy K20, TH400, NP-203(all time 4wd), all time 4wd hubs. I'm wondering if I can simply install locking hubs and make this rwd. I asked someone and he said that wouldn't work because the t-case would just send all the power to the end with least resistance, so when I unlock the hubs, it'll...

    14 bolt spindle nut torque

    I'm reassembling the rear wheel assemblies on my 1978 K20 and I can't find any torque specs for the spindle nuts. It's a 14 bolt full float axle and there are 2 spindle nuts with the spider looking washer thing between the nuts. Everything I can find on YouTube is for the new chevy 2500s and...

    Steering Correction

    I'm working towards installing a 4 inch lift on my 1978 K20 and just wondering which option to go with between a dropped pitman arm and a raised steering arm. (I've heard the raised drag links are junk). Also, I've heard that with a 4 inch lift I probably wouldn't to lengthen my driveshafts, but...

    2 or 4 inch lift kit

    I'm thinking of lifting my 1978 k20. I think the 4 inch would look the best but a 2 inch would be okay. I want to avoid having to mess with the driveshafts, so I'm wondering if I'll have to get longer driveshafts with the 4 inch lift or if I can just run the stock ones. Also probably going to go...

    Rim fitment for 1978 K20

    Looking into getting new rims. The originals are 16.5 so I have the option of going up to 17 or down to 16. It looked like there wouldn't be any room to get smaller wheels because of the brake calipers so seems like 17 is my only option, but also I don't know much about offset and backspacing...

    Bearing and race

    So I’m rebuilding the hub assembly on my 78 K20 and I only have until Friday. My AutoZone order keeps getting pushed back and I don’t think I’ll be able to finish by then. I’ve already installed my races (those were in stock) now waiting for my bearings to ship. But I’m wondering if I can just...

    Steering slop

    Ok so I just finished putting in a new red head steering gear, tie rod, drag link, power steering pump on my 78 K20. The slop in the wheel was pretty bad before, and I think it’s better now? But it’s still nowhere near as good as a modern car. Wondering if that’s just always how it’s gonna be...

    What size tires for 4 inch lift?

    I have this 1978 K20 on 33s and I believe it’s stock height. Thinking of putting a 4 inch lift on it (if I’m going to lift it, seems like anything less than 4 wouldn’t be worth it). Should I stay with the 33s or would they look too small and should I go with 35s? Also what brand would you...
