HI there, I'm selling my GZ Vacuum Pump, model VP- 104. It comes with the Pulley and the High Flow Vacuum Control Valve. This GZ Vacuum Pump made anywhere from 10 to almost 20 more horsepower on my Naturally Aspirated 440 motor...! It has approximately 2,000 Street miles. This Pump with the Pulley and the High Flow Control Valve sells for $925 Plus shipping, I'm asking $775.
I can provide the bolts and bracket so it bolts up to the LS7, you would have to buy the smaller pulley that mounts to the engine. That can be bought through GZ Motorsports
The smaller GZ Motorsports pulley does away with the stock idler pulley. The GZ pulley is a very nice setup, it's Billet and is much better because it has a shoulder on it and prevents the belt from slipping off, you simply bolt it on, apply tension and tighten it down and it's good to go...! I've heard of guys throwing their serpentine belt with the stock idler pulley. I've never had a problem with this setup!
