i have 380 hp plus a 150 shot and plan on upgrading the heads and cam later what injectors would be good and what hp are the stock injectors rated at.

 

1999 and 2000 LS1's have 26 pound, all other years have 28 pound.

I think most of the responses you will get for NA application will be 42 pound SVO's (also known as green tops).

I just recieved my 42 pound Delphi's from Harris Speed Works Putting them in next week.

 

your best bet is 42's you might want to play harder later on

 

Unless your going for a dry hit, your injectors are prob fine.
On injectors I went with the svo 42's as they are about 47/48lb'ers at our pressure.
