Ok so I really was trying to find this myself, I have found offsets before but I'm Missing something this time. I put a 2000 model gmc HD3500 intake manifold and injectors on an older model 454 in my 89 GMC C3500. I'm driving it and have it at least close. I used the offset from a set of 32# OR 36# Accel injectors to get it started because I couldn't find anything with the part #. If someone could shoot me a link or can look in a Stock bin for it, MAN I would appreciate it bigly!
Incase someone knows this manifold won't fit an older set of heads because there is no EGR ports on the manifold, I welded up a gasket surface on the manifold to seal off the EGR ports on the heads. It bolted and lined right up other than that mod.
truck weighs 6000lbs, mid 70's 454, .030 over bore, Comp cam biggest torquer for stock converter, TBI to MPFI 7427, $0E, injector part# 17109596, walbro 450lpr fuel pump, 4l80-85e not installed yet.
I REALLY appreciate this forum and all u that keep it up! This is a great resource, I love it even tho it makes me feel like a dummy most times ;) Thank u so much for all yall's help and future help :)
P.S. I may just go find a set of big LS injectors from the pull a part yard if thats an easier, better injector.
