Fuel Injection for my 454

[SBTork]

i've been doing some researching on my own over the last few months on adding fuel injection to my suburban and i've narrowed it down to FAST ez efi and MSD atomic efi. I am not close to pulling the trigger on anything yet so I am still looking to see what people have to say about each system. I've heard great things about FAST's products and I know MSD has some quality stuff too. I want to hear more about real world usage of MSD's system just because it's so new, but early indicators show nothing but positives from it. I think MSD's system is easier to install but I really don't think a guy could go wrong either way.
