Hello, just in need of some help for injectors. I'm not sure what size to go with. I have stock injectors at the moment that I believe are 28lb. Would they be ok for this setup if not what size injectors should I be running?

LQ4
LS6 heads machined 60cc
LS6 Intake
Stock LQ4 DBW TB
Stock LS1 rails
TS Cam 133/139 112
1 3/4 long tube headers

 

You can run the stock injectors with that TS 133/139 cam.
I believe you may have meant 233/239?
There is an injector chart sticky in this forum. If you think you'll be making around 425 whp, a good 36 lb injector should fit the bill, leaving a bit of headroom.

 

Lol, whoops. I meant the 233/239. I ended up purchasing a set of Fast 36lb injectors. Thanks for the reply!
