I recently picked up a very clean and well taken care of z71 l83 Silverado, well since nothing I have is stock I’m starting to order a few things just to make it a little more fun. So far it’s has a lift with 35/12.50/20s so it is a bit sluggish. I got dual exhaust ran, violent cai, superchips flashpak, and l86 intake and tb install for now. The guy I got it from said he had the trans built 10,000 mile ago with billet stuff??? Who knows if that’s true or not! Here shortly I’m looking for order long tube headers, catted y pipe, ported heads and either the btr or tsp stage two cam. Which will all be installed at once to get tuned afterwards. I’m not looking to make a race truck or go boost but to have a decent truck that isn’t a slug with 110 lb tires to move around. Is there anything else that could be done that I’m missing in my research to gain a few Eagles or other easy mods that will not hurt drivability to much? And has anyone swap to the 6l90 tc and what are the benefits of doing so?
thanks for any advice or knowledge
