I'm still running the stock 19lbers 
But if still got stock intake, heads, and just a Hypertech chip... so I don't think its too bad right now. I would like to move up to 22 or 24lb with a custom chip after I do some intake mods

I am running the stock 19's in mine too. I have a Crane Compucam 114122 204/214 .423/.446 lift, a/c delete, hooker headers, Flowmaster exhaust(3 inch), Accel Kool Blue filters w/gutted air boxs, home made ram air box(s). It seems to be ok with the stockers so far but I am getting my friends 22lbs injectors from his 87 Iroc-Z 350 since he is upgradind soooo I plan to get those flowed and add a custom FastChip by Ed Wright. I say go with the 22lbers there and you'll be ok. just burn a new chip.

I'm running #30 Accel's. To run a larger injector you will need a PROM that is matched.

Wow, I know this is not what or where to ask this but...what kind of time have you gotten outta that 305 with that SC on it???
I have been thinking of running either nitrious or getting a supercharger, I would love to hear what you run and if it was worth it(I am sure it was).

I have not run it at the track yet. It will be on the strip this spring. I can tell you that I am very pleased with the performance of it.
