Really bad stumbling on the highway (400 small block) - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have an '81 GMC K2500 350 Quadrajet, four speed manual, NP-208, Corp 14 bolt semi-floater long bed with twin tanks, tilt steering and sliding rear window. Non a/c, no cruise. I'm the second owner, and it needs a lot of work, but it's real straight and hardly any rust at all. Payed six hundred bucks for it, and I'll get it on the road by this summer.

I prefer to run mechanical fuel pumps because they work in sync with engine rpm.
