Seeing as my own project is stalled out, my dad has asked me to replace the 5.3L in his truck with a 6.6L. Can anyone recommend a good, reasonably priced 42lb fuel injector for a Chevy Gen3 engine? Ideally it's something that will fit on a 2001 Silverado without any adapters or anything. The engine should be ready by Thanksgiving, so I have a little time, and I'd prefer new.

That Packard 4 tab connector and Multec 2 short outline is not a common one at all. I looked through our application database and the most readily available injector I can see with the same outline is for a 2000-2003 Chevy S10, which is 23 lb/hr.

If you can space the fuel rails higher for a taller injector, the 1998 - 2002 Honda passport has the same connector but will flow 26 lbs/hr

You really need to convert over to an Amp or USCAR connector to open up your injector options.

John speaks words of wisdom.

I would swap over to a LS7 injector, but as John said, it will need a USCAR connector. The USCAR connectors and terminals are readily available, so with a decent crimping tool and some care, changing the connectors is not a big deal.

I fear no wiring project, so I'll look into that. Thanks.

You could send your factory injectors out to get reflowed. People are "decapping" the factory injectors to turn them into 64lb/hr setups. Only difference in the flow rates are the diameter of the holes in the end cap.

Unfortunately, my father passed away from a heart attack last week. I've cancelled the project and the truck is now gone.

Thanks. It was a real shock even though it was kind of expected. His health had been declining for the last year.
