Fuel Injection for my 454

[Gumby]

Holley system has to be the best as its turbo/blower/NOS ready, many of the similar system like fast can't do that.
Even if you don't plan on it, the Holley system is ready for anything you can toss at it and it can auto tune it for you.

fast does look cool with the low mounted injectors but can't handle mods.

It cant do forced induction. It can do nos with carefull tuning. That is the only thing i dont like. There is a guy on ls1tech with a procharger but not sure how he is doing it. But it can handle 600 hp single and 1200 with duels. I seen the msd system at goodguys resently and it looks like a great system. It can also control timing which is a nice feature. If i was to buy again i would look at the msd and fast. I dont like the holley because the injectors are above the throttle. Just a fancy tbi in my mind.

You're not alone in that line of thought....

I agree to but after lots of research, others of the same price can't handle as many mods, or it would be faast hands down for the below the plate injectors.

I do plan on injecting mine in the future, and I'm convinced that the FAST EZ-EFI is the one for me. The only other one I think I'd consider is the Atomic EFI from MSD, but I have a hard time buying an ignition company's first try at a fuel injection system. Plus, a lot of it's appeal is the returnless fuel system that is accomplished by cycling the fuel pump on and off which I'm sure is not good for the longevity of the pump.

One thing the MSD does really have over the FAST is that it controls timing, and a lot of the injection guys say that is very important. Although, FAST has been around the block a time or two, and I'm sure they have a pretty good handle on things.

My vote is FAST!
