Default What injectors?

I have a Iron block 6.0 that has been bored and strocked to a 6.2.
It has GM ported LS 3 head, LS3 intake and LS3 injectors.
The cam specs are: 227 INT 235 EXT DUR @.050 lift
613 INT 620 EXT Lift and 113.0 Lobe Sep.
Should I change to a different injector, or ?
I presently have a 80mm throttle body, but am thinking about getting something bigger.

Thanks,
Rob

Default INJ-60 650cc Flow Matched

Hi, I supplied Jacob (Darth8) a set of INJ-60 fuel injectors (Flow Matched with Dead Time Reports) that preformed BETTER than the smaller ones he replaced.

Read that report Darth V-8's thread.

I can supply the same for your needs.

LS3 injectors are 36lbs @3bar, you should be fine at 410HP, unless you plan on pushing more later on.

Stock ls2 or Ls3 injectors will support that hp.

Maybe I'm barking up the wrong tree.
I'm looking at what bolt-ons I can change to pick-up a little horse power.
If I replace my throttle body with say a 102mm and a different set of injectors, will that work?
Or should I keep the LS3 injectors even with the larger throttle body?

Thanks,
Rob

Stock ls3 injectors will be fine even if you replace the throttle body. The throttle body will be a very small gain if any most likely.

Put a big mouth 92 on it for the throttle response and a couple of horses. Injectors will be perfect. I bet you will be at 80% duty cycle with the big mouth and gmpp heads being a stroked 6.2. Your pistons will be moving a lot faster. 420 is low for that short block and what you have. I picked up 5 mph in the 1/8 with a real good y pipe 3 into 4" with a dump in the 4" section. That's 50 hp son.
