Here is one stupid question, what are the LS1 injectors stock? Aren't they 28#'s......

Anyways...

My duty cycle for my injectors with my 228/232 .588/.595 cam is 98% So i was thinking that i was going to upgrade to 42#'s. What is a good one to go with? SVO or isn't there one called red top or green top

Thanks

98's were 28lb, 99-00 were 26lb, 01 and later were 28's. I odered the 37lb injectors straight from racetronix. They will flow just over 42 at 58psi.

All above info is correct. I used the Racetronic 37 lbers in my previous car, and I have their 42s and pump in my current car. Depending on what your future plans are will determine which size would be best for you.

I was planning on going big (42#'S) just incase i do N2O or FI

FI you would probably need even bigger, but the 42s will be nice with a shot of juice. I'm having no issues at all spraying on top of my heads/cam with my 42s and Racetronics pump. Good luck!

I am in the same boat as you.

I plan on going with Racetronix's 42# Injectors (280) with their Plug and Play Setup for 249.99.

I had a used set of 36lbers from my old GTP sitting around and got 2 extra's from another buddy with a Regal GS for $20. They run around 40 lb/hr at 58PSI. The 36 lb/hr rating is at 50PSI. You can find them all the time on the ClubGP.com board when people upgrade to the 42 and 60 lbers on the 6 cylinder cars.

They are a stock GM injector for the Supercharged V6's and fit perfectly. I went from 98% duty cycle to about 68%

The answer to your question is yes Ford has a red top 30# injector that flow somewhere around +36# at 58 psi.
