It is the Holley MPFI kit for BB Chevy engines. It was recently discontinued so not on their website anymore. The intake manifold was an EFI version of their Strip Dominator. I'm not a fan of this kit but it is what the customer bought and brought to us to use. In the end it made decent power and worked fairly well at WOT but always ran rough at fast idle. We'll see how it works in the car. Not much we can do to fix it since I think the problem is inherent in the intake manifold and/or the fuel rail design. Could be why Holley discontinued the product.
