New member. Does anyone have a preference (or stay away from) manufacturer/source for the upper intake, spider etc? 1999 (old model, Feb. 1999) 5.7 vortec GMC K2500. Thanks,

I found another thread on this. Thanks for the site. Very helpful. I've had the truck for about 15 years and very few problems. About 220K now and its like the Energizer bunny. I'm glad I found this place though.
