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.
