Chevy step side k10 4x4 1975 1st year no smog test needed. Fully restored new Chevy short block 383 engine, holly master, everything under the hood new, everything u see the truck new. Everything inside new. Just put 4.56 gears. 35” tires. Truck is immaculate. It’s a 4 speed but 1st gear is a granny gear so I only run it 50-55 mpg rpm starts to get high. Last thing I wanted to do was put a 5 speed in it. Super smooth shifting and would cruise freeway 70-75 easy cost 4200.00 I haven’t done it yet. Added a/c to it as well and cluster gauge set up. Has 440hp with everything g added and feels like it could pop a wheelie. Reach me 661-477-5008 Steve truck is in bakersfield. It was a 2 year restoration project just finished last month. Over 75k put into it.
