MSD atomic EFI is it worth $1800

[DonutCr3w]

Hey guys i want to upgrade from my carbureted small block and possibly going for an EZ-EFI unit on the crate 350 i have at the moment. If anyone has any experience using these id like to know how they are and if they're as great as theyre cracked up to be and if theyre actually worth the cash, thanks- Casey

I have a Fast Ez-efi on my car. I love it! That thing runs great it was easy to hook up and I have no problems. At work we used to sell the fast now we deal with MSD. The msd is a nice setup. Easy to hook up. Not a lot of wiring without a bulky harness. The fast harness isn't bulky but is bigger then the msd. Overall the msd is a nice setup and no need for a fuel return like the fast needs. Any questions feel free to ask.

They all have their ups and downs. As long as you stay with those two. I have heard stories about holleys efi and professional products powerjection is junk. The new edelbrocl efi looks good as well, I have yet to use that.


Just for referance I have a 434 stroker olds. I got 10mpg with taking it easy I now get close to 13mpg with my.foot in it. With the throttle response you can't keep you foot out of it.
