Like I said, I have installed all of them pretty much on 5.0's and for reliability I'd buy a Vortech/Paxton. My 93 LX HAD a ProCharger but they were douches when a seal went..took bearings out...then the impeller into the volute.

I tried to get the parts to rebuild but they would not sell them. This was when the car was still my cousin's but I did all the work for him pretty much. So on went a used Vortech and never looked back. I would just be careful with the self contained ProCharger units and want good pics or be able to inspect in person. They are good sueprchargers though, I like the sound of them.
On an SN95 I am not real fond of the ProCharger install with the filter right above the driver header.:smash:
NOVI 2000 are sick if you can find one used as new they are $$$$$. They have a sick gear case in them. Here is the NOVI 2000 I had..it was for my F150 lol.
This car here ran high 9's at 142mph with a 347 sportsman block, YS-Trim, AOD, and drag radials.
