I'm 99.99% sure no 3rd gen LS swapper (or maybe even any gen swapper) is interested in those @ $2500+ to eliminate some wiring.

Re: FYI-Atomic EFI LSx kits
Those kits are pretty neat...but very pricey.
If you didnt have injectors, wiring, fuel rails, or a PCM, it might not be the WORST investment. It would still cost more than sourcing the parts obviously.
I dont think these are aimed at guys that have the parts already, or have a running car. These are for guys that buy their LS in a short block, and add all the bits and pieces.
And those terrified of wiring with money to burn

Re: FYI-Atomic EFI LSx kits
Ah didnt even think of that... Are there stand alone 4L60e or other auto trans controllers? Even if there are, thats even more $$$.
I always associate swaps with T56's since they're usually the popular choice.

There are stand alone 4l60e an 4l80e controllers, but they are pricey. Makes that 2500$ kit 3,000-3,500 for some guys.

Re: FYI-Atomic EFI LSx kits
the Holley Hp sytems are half the price and very clean and come with a ecu and wireing not to mention boost control SD tune self learning fuel tables wide band O2 2 and 3 step 4 stages of nitrous control and theres more you can do with them THE downside the hp does not control a trans the dominator does but at 1980 dollars you can have a HP and TCI ez TCU stand alone and have full control
the Atomic does look cool though
