    I'm looking for a descent set of truck manifolds to fit my 5.3L. It is a must that I find a set without A.I.R. and without EGR. PM me...

    If you run out of options I have a set with EGR but no AIR.
    Good luck

    Thx, but EGR is the reason why I can't fit those manifolds b/t the rails.

    Appreciate the offer. Found a buddy close by who gave me a set of 6L mans (no EGR/AIR). If you have a cutting torch, that'd be good. MY C10's frame rails don't bend outward as wide as the NBS trucks. The new motor fits tight, but is in firm. Notching will take care of my issues. Thanks, again!

    FYI... I'm told that LS1 manifolds would fit tighter... here's the problem with the truck manifolds (minus EGR):
