Does anyone have a GM 4.3 vortex engine out there that they have been experimenting? I think the year range is 1999-2005.

I have a 2001 4.3l that is bone stock save for a K&N panel filter. I am still in research mode before I start adding things to the motor. I'll posting results as I get 'em.

On ebay I bought a knock off KN for like 6o bucks.Same exact thing. Comes with everything you need and looks and works the same except paying all that money. Also the intake part comes in different colors.I may still have the ebay link. and I'll pass it on. This was one of the ways I thought ,so you have a little more room to work with and gives a little bit better performance.
