42's from RaceTronix... Its what I run on my H/C/I LT4 and tunning was nice, no issues.
401 rwhp 375 rwtq
I imagine your 383 would move more air than my engine.

whats AFR's sorry lol? not sure bout how much hp and whatnot with stock injectors and tune i never got a chance to dyno.... and yes 60cc is what i was told when i ordered them... and my cr is 11.5:1 it was 10.5:1 from factory i think..
are these the right ones your talking about? Bosch 0280155968 Fuel Injectors
i also found some on fuelinjectorconnection.com
they are the bosch BLUE DEMON 3 modified
which ones would be the easiest? no fitment prob. or connector issues?

I also suggest slowing down. Judging by the parts used in your build you have a lot to learn.
You can't just swap in larger injectors - you need a tune or as mentioned above you'll dump tremendous amounts of fuel into the cylinders, likely washing out the rings and doing other very bad things.

If you're getting a 58mm TB then make sure you have your intake ported to match it.

I have a used BBK 58mm from Jason Short but as soon as Xmas is over I'm going TPIS. But if you're on a budget search the for sale sections in here and camaroz28.com. Someone is always selling a 58mm TB.
For now put your $$ into your heads and intake. This is where you'll make most of your power.
