I'm trying to figure out what I really need, don't need etc. when I eventually get a 383 or just rebuild my 350.. My Jimmy is an 80, it has an air pump (to put air into the exhaust manifold?) If I get headers what happens to all that crap, vacuum lines, air pump etc.? There's vacuume lines everywhere on this thing, I see engines in trucks and cars with none of it, simple, clean engines. Will all of this crap work with a 383? Would I be better off removing all of it? Also does the canister thing and all of those round silver things that vacuume lines go through ever go bad? p.s. can you post a pic of your engine bay if you don't have all of the emission crap.
