Re: 2000 Chevy 3500 454 essential mods?
Did you ever get that truck?
I've seen/heard/read that headers might be the single most beneficial upgrade to the later 454s. The Bosch injector swap is supposed to be worth the effort (and while you're in there replace some consumables: distributor, if its worn; fuel pressure regulator, oil pressure sender, fuel lines, gaskets, etc).
