I still say the best bang for the buck, and the most fun I had with my truck, was stock turbo, built trans, and lift pump. Around 500hp or so, I ran high 12s, and you can't beat the responsiveness of the stock VVT on the street. Not to mention it sounds pretty mean! I have a few friends with LBZs who have done lift pumps and we put PPE kits in their transmissions, and I always tell them to stop there!!
