Re: Mr Green Jeans - the 69 (or not) chevy, er gmc, project

I'm getting the distinct feeling that I will end up doing everything on this truck twice. Because I upgraded from a 5.3 to a 6.0 and also because of the Dakota rack I installed, I was having trouble routing the steering shaft from the inside of the frame and could also use a slightly bigger header and exhaust. Doug Thorley headers fit nice but hang way over the frame rail. I bought a set of Doug's headers part # D314 that tuck tighter, have a larger primary, and will upgrade me from 2.5" pipe to 3".
