Hello, I  am a new member located in Norway, my truck is a 2003 Avalanche 2500 with 502cid BB, maybe some of you out there know if there is a supercharger kit for my truck available.
One of our Site Sponsor sells them for the 8.1 engine, if you have a true 502 I don't know about that engine here a link.
