Fuel Injection for my 454 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

The MSD Atomic EFI is similar to Professional Products TBI. All-in-one EFI system built into the the TB. Good price point too. It will also control timing as well. Made in the USA. And in some cases can be used returnless. The only reason I didn't buy one for my last swap was because they aren't offering a TPS output with it, so I'd have to add an external TPS for an electronic trans, which I think is a stupid hack. I've already asked MSD support to consider including TPS output in a future version.

I have a fast ez efi on my burb. Love it. Started and ran great at first turn of the key. The master kit with pump and hoses and fittings can be had for under 2000 if you shop around. I got mine price matched from atlanticspeed threw summit. Will never look back.

p.s. I went from 7 mpg with carb to 14 mpg. I suck at tuning carbs.

wow.. I'll look into that option some.. my main concern is what I'd will have to change on the motor (cam, existing MSD ignition, heads, intake, etc) to use something like that.

As long as cam produces 9 inchs of vaccum the efi will work. It is made to bolt on to any motor with a flange for a 4 barral manifold. 4, 6, 8, and maybe 10 cylinders. All it needs is a rpm siganal. That is it. You tell it how many cylinders it has and dipplacement and what idle speed you want and air fuel ratios you want and turn key. Works on my lq4 with a cam.

It does not control the ignition at all. It only needs a rpm input from the msd box. Like the tack signal wire.
