Barley got my 4th gen camaro going in for a motor rebuild pretty soon an I was just wonder around how much hp would I gain by adding these bolt ons I just got ,throttle body spacer. Intake, long tube pacesetter headers with x pipe, 4.10 gears for the rear end and a shift kit for the stock 4l60 tranny the tranny is getting rebuilt to when it goes into the shop an Ima spray 175 shot of nitrous (wet kit) thank you guys

Guessing 460ish rwhp if everything else is stock. The 4:10 gears will hurt the dyno numbers but help on track/street. While your rebuilding the trans might be a good idea to swap in a good converter. Something spec'd for spray. Maybe one from the Yank PAS series would be a good option.

thank you what gear ratio should I have went with

If dyno numbers are all you care about the lower ratio the better. But, your gears are good for real world racing. That's all I was getting at.
