04.... thank you for the reply....the p600b was actually one of the most popular blowers procharger has ever built. I would guess that sales of that blower still outway the new P and D series. It was produced for the lt1, a ton of small blocks, 5.0's and the 96-98 4.6's. A guy on the corral has one and has over 200k on it, and 300k on the stock block. Its a very strong blower. Ive done a little research, and many people feel that its one of the most reliable blowers out there, but not too many people have them on 96-98's because of the vortech and paxton and ati p series that came out right after it. However, like a vortech on the 96-98 cars, you have to tap the oil pan. However, the kit is intercooled, which I prefer to the aftercooler and moving the battery back with the vortech. Just wondering if anybody out there has any more input on these setups, since the vortech is so common. Again, thanks for the reply and Ill be hollering atcha if I go with the vortech. I have a complete 96-98, 3.6 pulley kit with low miles and the aftercooler lined up to buy if I dont go with a procharger.
