I am not sure. I believe the 90-91 SD version used 22#, based on what I've seen in the "hack".

94-96 LT1 Corvettes have 24lbs injectors, but I believe the TPI Corvettes are all 22lbs, and so are the 92-93 LT1's.

88 350, I know exactly which post you are talking about, and it had me scratching my head.

Some guy posted, and said that in '85, the Vettes had 24# injectors. Then I stepped in and asked for proof, since I am running injectors from an '85 Corvette.

But untill somebody can prove it, I would say they are 22# because I am using them on my 305, and only run a little rich. I would think if I had 24#'s, I would get a code 45 or something.

The only year l98 vettes came with a 24# injectors was 85. All 85 vettes. goto www.corvetteforum.com and look it up on their message boards.

They vary some by who's doing the testing, and or reporting.
Some use a 3 bar presure standard and others 39-45 PSI, there is no standard.

I personally wouldn't fret about 2#/hr.
I tend to go big and leave some head room.

Diggin' this up from the archives.

The 85 Vettes ran a fuel pressure of only 35lbs, not 43 like in all other years. For this I'd imagine they would use a bigger injector to compensate.

GMTECH, I'm running 24lb/hr SVO injectors on my IROC (the svo injectors are about a 26lb/hr injector with GM fuel pressure) and although I run rich as hell, I don't throw any codes.
