need injector knowledge
Does anyone know what size injectors i would need to run to get best performance from this setup? I have read how people stick with stock #19's and also jump all the way to #32's. Heres what i having done. Im keeping it N/A...
*10.5 : 1 forged pistons
*forged rods
*comp cams stage 2 xe270 cams
*beehive springs
*heads are port matched, ported and polished and 3 angle valve job
* LT headers, o/r h , LM2 catback
*Full bolt on's-75mm T/B and Plenum,UDP's, CAI ext...
* dyno tuned when done...........
my main concern is will my stock injectors be too small and if so will 24lb injectors be enough to achive all im going to be able to... and i may add a 100 shot later. any info would be great .And if anyone has a simular set up can u give me a idea of what kind of HP numbers i will be looking at to the wheels? Thanks!

RE: need injector knowledge
You might get away with 19 lb/hrs, but with whats basically a forged shortblock you could make 320+ WHP.. which would be enough to warrent going with the 24s.
The simplest thing is to try it and see, if your tuner says your going lean and your duty cycle is to high, get the 24s.
