@Giant Rock

Thank you! Its been alot of work, and still is (getting a new trans atm and needing paint soon) I'm not sure about that kit in particular. Mine is 2" blocks in the rear (not the best) and some brand of aftermarket lift springs in the front (was on it when I bought it, but I think skyjacker, or tuff country)

I've changed the shocks out for skyjacker m95s with poly bushings, I also used ORD's Kevlar leaf spring bushings, ORD's upgraded front spring shackles, and their sway bar quick disconnect kit. All of the body bushings and engine/trans mounts etc. are new regular rubber. All in all I've been very happy with it. I am sure there are better setups out there, especially on the rear end.

I've also been pretty envious of the ones on here with 35s and 4" lifts. But I fear my gearing and 700r4 wouldn't like turning anything bigger then 33s.
This is my 78 K5 with a 4" lift and 35's. It also has 1 1/2" spacers all around. I have a 4L60 with 4.56 gears running the 383. It's producing about 400hp and a little more tq.

That looks great! Your 383 and gears are a big game changer. I'm betting that is a very fun setup.

Thanks, runs like a scalded dog up to about 4500rpms. The steering is a little vague with the big tires. Maybe a crossover kit would help.
