For Chevy Vortec 454.
I have a 1998 K3500 and the only thing missing is the supercharger. The rest is there, computer, pulleys, fan, etc.

If I can't find one, I need to pull all this off and go back to factory and sell those parts to someone that needs them.

try flreabay, the have a ton of oem type blowers

Looked and looked before. They have all of them but this one.....Hell if I could just find a junk one, other companies can rebuild them.

never knew a 3500 came with any supercharger.

This thread must have brought me luck. I checked it and then Bam! One on ebay in great condition, the whole deal plus EGT setup. Got by for 1800 with shipping included. Can't wait....I know Big Red is excited to get that power back again.

Mike, it was a very expensive, 12k I think at the time either option or dealer option. I have seen a few and some Suburban's as well with this. An extra 150 HP with tons of torque. Should pull great and light up my 315's whenever I want.
