Hi everybody, This is my very first post, although I've been reading up on everything on here for awhile. Anyway,.. I am considering removing my smog from my 87 k5 w/305tbi. I've heard different stories on the difficulty level. Is it just a matter of removing the A.I.R. tubes, smog pump, and replacing the manifolds? Or is it more complicated than that? This is my everyday work truck,.. so it can't be down for more than a day. I'm also wanting to replace the stock manifolds (passenger side has recently cracked and left a hole you could put your finger in) and I have come to the conclusion that I will be wanting to use Shorty headers (after smog removal). Will just about any shorty for a SBC work, or can I possibly get some suggestions of some that would involve the easiest installation? Cash is an issue, so Thorley's are out of the question. I will also be using the local exhaust shop to make me a new y-pipe. I do currently have 3.5" behind the y-pipe back, along with a hi-flow cat and a flowmaster. I appreciate any input and suggestions. THANX!!!
