Re: Injector Identification/flow
Maybe clean the injector up and check it again real closely, I know I've seen 6's as 8's etc.

Re: Injector Identification/flow
OK, try this number: 217-2282
Supposedly that's an AC Delco number. I need the lb/hour rating please.

Re: Injector Identification/flow
There are 5 pages of answers on the ACDelco website, by using the "Find out what vehicles use this part number" feature, along with the ACD pn 217-2282. Most of them seem to be 7.4 liter v8 models.... from 1994-1997 (VIN engine code N), along with earlier applications for the 4.3 liter v6 (VIN engine code Z) back to 1988.

HTH.
EDIT: I realized I never answered the original question: since they're injectors for either a 4.3 at 9-13 psi, or a 454 at 9-13 psi, or a 454 for 28-33 psi, then then injector rating will be approx 90 lb/hr with 28-32 psi (as in 94-95 454 SS), or around 52 lb/hr with 10 psi (conventional 4.3 use).

Re: Injector Identification/flow
Well, 45 lb/hr isn't that far from 52. The "error" is on-par with 90/75. The key is that they're 454 injectors.
