Ok guys,
I need some Flow-Matched injectors for my 402 Stroker. What brand should I buy ???

Interested as well, I'm in the same boat.

Builder wants to go with Delphi 42s for $305.

I ran 30# SVO's on my H/C 346 and have 42# RC's on the 418. Best buy new are probably going to be the 42# SVO's, but the Delphi 42's at $305 sound like a great deal too! I'm sure lots of other guys will chime in here with their opinions.

I run the SVO's 42#, don't know the price...

The Lucas/Delphi 42#s seem to be a popular choice with the N/A LSx crowd. Tuners appear to like them, as well.

You weren't running 28#s in your 11 sec 383, were you?

I went with the RaceTronics (disc type, similar to the Lucas), bought them direct. I'll shoot you a PM with a link if you want to look them over.

Thanks for reminding me, I was looking at Racetronix awhile back but forgot all about them. I'm finding out what the differences are between them and the Delphis.

I had Racetronix in my 02. Worked great, never a problem.

Thanks gang.

Judging by some of the sites I've looked at, the Racetronix 009 injectors are the same thing as Delphi and Lucas injectors. Even the Racetronix site has both Delphi and Lucas part numbers along with this blurb at the bottom:

Performance advantages over pintle injectors (i.e. Ford / Bosch & Accel types) as listed by Delphi:
• The flat mating surface ensures that no excess fuel is present to evaporate and therefore, no deposits or clogging can occur.
• Compatible with alternative fuels (i.e. E85, Methanol)
• Longer service life
• High-speed disc action allows wider dynamic flow range for improved idling
• Quieter operation
• Revolutionary disc design resists build up deposits which can affect fuel flow.
• No Fuel leakage for quicker starts

Can anyone verify that this is the case? I also found info about flow-matched Delphi/Lucas injectors and the only difference I saw was this:

Silicon grease supplied to lubricate o-rings prior to installation.
Dynamically flowed and grouped to tighter tolerances than factory with Racetronix new injector flow bench

I found this info on non-vendor sites, so no links provided.

My builder says the Delphis he's hooking me up with are flow-matched.
