What injectors for my setup?
What injectors for my setup? I was told by a few that my stock injectors might be borderline so i want to ask a few people who have a little more experience than myself on how many lbs injectors to go with for my set up.
My mods include:
Cold air intake
Ported and descreened MAF
LS1 hot cam
1.8 roller rockers
5.3 ported and polished heads
shorty headers and custom exhaust
On my 2000 ls1 c5.
Im not positive but I think my car came with 26lbs fuel injectors.

The stock injectors should be fine, however the SVO 30's wouldn't hurt. At 4 bar they put out around 35. If you have the car dynoed the AF will tell the story if you start to go lean up top.

I just said that in a different thread. Great minds think alike! 42's would be overkill in this case though. I would only plan on 42's on stock CID if you were planning on running FI. A bigger motor would definitely make for a set of these though. Honestly in his case right now a stock injector would be just fine. He is most likely gonna be around 90-95% max duty cycle at WOT with a hot cam and bolt-ons. Hard to say without EFI Live though.

FWIW, I am using SVO 30's in my 408, no issues. I was thinking about upgrading when my 408 short block was being built, but Erik @HKRacing and Thunder Racing told me not necessary.
