Looking for help on a holley hi ram I have a 2003 5.3 with a MS3 cam, Vic jr , 6010 msd and 750 double pumper. I am wanting to install a holley hi ram. But don't really know where to begin. I plan on ordering the intake , fuel rails, throttle body and a aeromotive regulator.
Can I use the stock injectors or should I upgrade them to something larger? I can't use the stock ECM and wiring harness because it's a drive by wire and this is in a 55 Chevy. Will the 6010 work or do I need to find an older ECM and wiring and have a tuner work it over. I plan on upgrading to a forged 408 and maybe a turbo later on but this is what I want for now.
