Default Need help deciding on 42 lb. injectors

I need some help deciding which brand of injector to go with. I know I need some 42 lb. injectors to supply enough fuel for my H/C and dry shot.

Originally I was going to get the FAST injectors but the price on them has gone up to $600-$700!!! That's crazy.

I done a search on most of the injectors available but I'm still undecided. The Racetronix injectors seem to be the least expensive but I'm also considering the Ford SVO injectors as well.

Should I be concerned about whether the injectors are flow matched? I've noticed some sponsors advertise flow matched and some don't.

What do you guys think I should go with? I already have a Racetronix fuel pump kit so I just need the injectors now.

I run SV0 42# injectors with my Racetronix pump, stock rails on my 383.
they were fine out of the box...however I did have them flow matched after a fuel incident. My engine builder did mine for $60.

The Racetronix injectors are flow matched already.

We offer the 42's in both non-flowed and 1% flow-matched sets.

sorry new to injectors... flow matched meaning they will flow correctly on the stock tune? so a basic bolt with capability of flowing more than stock? just trying to clear some stuff up. thank you

No, you will need to tune regardless of whether you get them flow matched or not. Flow matched means that the injectors all flow nearly identically. There can be quite a variance from injector to injector if not flow matched.

Any benefit to upgrade injectors on just a bolt on car? Headers, LS6 intake, Underdrive pully. I use the car for road course duty so it sees extended high rpm use.
