    Need inector help

    I have a 418 with 40lb Accel LS1 style injectors. I can't get the correct injector data from Accel. I have been trying for two weeks. Holley is supposedly talking to product engineers but I am at the point of just buying another set. What is a good injector for the 550 fly wheel range? I need LS1 style injectors to fit rails and intake. Any help would be greatly appreciated.

    I have the Bosch 36lb GTP injectors. They flow 40.5 on a ls engine. Should be around 80-85% at 550hp. All the information is posted about them on this forum.

    The 42lb green tops (48psi at 4bar) time really well and that data is published..

    550hp on 93 octane on a NA setup is doable with them

    What brand? FoMoCo Bosch ? I looked into some green tops but couldn't decide which was best choice.
