yes you can use them. they are 24.9# @ 3 bar stock tpi fuel pressure. you might have to grind the fuel rail mounting bosses down 1/4" - 3/16". 3/16" worked great for me. prom changes are required if not it will run too rich.

The difference in length of LS1 injectors and our stock 22#/hr injectors is exactly 0.10", the LS1s being shorter. I just checked this out 1 hour ago. I still have the factory injectors from both my '87 and '99 Camaros.
