This was the first Camaro SS I have done. It is a 2010 with 56,000 miles on it. Customer wanted a nice driver with great manners. I couldn't use my normal dyno since it was down for a while and now is all backed up. It ended up going 502/445rw on an unknown dyno jet. We had a ton of problems with the dyno and WB so only got a couple clean pulls to check the fuel. Motor was pretty hot and the weather wasn't great. We actually had to run the WB into the cut outs to get a reading. The funny thing is, with the cut outs open we lost power. So these numbers could be higher if we could have closed the cut outs. Mods are.

ARH Headers and cats, stock mufflers
AI 275 heads stock compression
YT UL rockers
stock gaskets
Comp custom cam in the low to high 230's with .615ish lift on a 113
FAST 102 with 90mm TB (the miss match is hurting us)
UD pulley

I think we are going to get the TB swapped out for a 100mm and get it on my regular dyno in a week or so. Are these numbers good, bad, what? The customer didn't seem overly enthused.

Sounds about right for a h/c 5th gen on stock compression. Heavy YTs arent doing you any favors.

Yeah, I felt that at 6,500 exactly. The cam was still on the rise and then valve float. I used them in the past on my other builds with no issues at 7,000 so they went on this build. I wish I would have had the heads milled more but the math was giving me right at the safe limit on PTV. But when I actually checked it I had a lot to work with. Compression would do wonders for this combo. I thought the numbers were on par with the little research I have done.
