Re: 1986 GMC Sierra Classic - Flatline
Below is the carnage, let me tell you those exhaust manifolds put up a fight. I only broke one bolt and one spark plug. This poor truck hasn't received much love in a long time.
After I finish hanging both new headers, I will finish the exhaust and move onto the intake and various wiring.
The next mod will be the cam while I am in there with new lifters, springs, seals, retainers, timing chain, and a new one piece metal oil pump shaft.
