The FAST 36 lbs. injectors would suit you just fine. They are the latest generation Bosch design that employs a stronger coil for faster response. They also benefit from a better spray pattern than the previous Bosch designs. They can be found for ~$300 to the door.

Remember that you will end up with a larger injector because of the 58 lb. fuel pressure on the LS cars.

I have a post on this as well.
Where is the best place to get these from?
approximately what kind of MPG should you expect to lose?
Has anyone actually done a comparison with dyno's "before after fuel injectors with 420+rwhp".
Maybe I should do a search first.

I would stay away from Accel injectors; based on flow testing I've had done on two different sets of Accel injectors, the results were less then stellar.

For 600 HP at .5 BSFC with 85% duty cycle, a 44 lb @ 43.5psi static injector flow rate would be the correct size. Adjust injector flow rate according to actual fuel pressure.

I have had good luck with the FAST 36lb injector, which is a Bosch 0 280 155 868. The FAST/Comp Cams part number for an 8 pack is 303608. I have purchased two sets from a guy on ebay for ~$300 shipped.

The part number for the FAST 42lb injector is 304208 and is Bosch 0 280 150 558. Flow information http://www.witchhunter.com/flowdatapix/b0280150558.jpg

HTH,
