[QUOTE="CobraBob, post: 3665125, member: 6727"] 2.93 and 4 lb. lower is a good choice. If you don't want to mess with the lower, consider a 2.90 upper only. Depends on how much power you're wanting to make. To be honest (with an unported blower) a 2.90 upper only will get you in the neighborhood of 455-465rwhp with the other mods you have, depending on your tune. I made 457rwhp with the 2.90 and that was with the stock headers. You'll also see moderate boost increases (12-13 lbs.) with less heat soak. You can then always add the 4 lb. lower later, especially if you port your blower. You might also consider adding a larger heat exchanger (Gords or LFP). IMO it is a very wise investment. Heat robs power! And don't forget the suspension mods. Click on the Red Pill below. [/QUOTE]
