this is the one I have 607CFM It came in the Holly 2DI pro-jection kit.

The controller and harness went with the truck, I might beable to get it if anynes interested in it.. it will control a OEM TBI unit.

I put in a Helix Power Tower 1" spacer under stock TBI and a K&N FIPK. I think I paid under $100 for it a few years back. The K&N / spacer combo gave me some nice mid range power on the highway, but my low end dropped off.
FYI my combo hits the underhood insulation.. it's rubbing the intake tube of the Filtercharger but it does fit, but with no room to spare.
