I'm still rocking the OG Integrated head 250 in my '78. I bought some nord-loc nuts to solve my blowing out exhaust gasket problem. Honestly, I would prefer a non integrated head 250, but the engine runs ok. Mine is a short bed step side with 3.73's in the back and a T5 trans. It's not bad...I really don't use it as a truck, except for the occaisionally helping a friend or family member move. I think I get 18 mpg on the hwy which is damn good for an old heavy chevy. With the old 3 spd, I think the best I ever got was 13mpg.
