There's nothing wrong with that! 116.xx trap speed is awesome. It may not be a dyno queen but it sure runs hard! 
Tsp 231/237
Agreed, 115-116 MPH on stock heads is moving on out. Sure there are faster cars, but that ain't bad at all considering you're not on slicks and skinnies, and you didn't mention anything about race weight.

372/355 is the best I got out of my 231/237 with PS LT's, LS6 intake, and S3 ported TB. I also have LS1 edit tuning. The car runs great, just doesn't show high numbers on the dyno, which is ok. I need an UD pulley. Any ideas how much that UD pulley is worth HP/TQ wise on a cam only car?
my M6 car with full boltons, raceweight of 3400, and tsp 231/237 cam on stock heads went 11.46 @ 120, dyno'd 408rwhp/390rwtq through a moser 9" with 4.11 gears, on motor. This was on a nitrous tune though... there was definately more left on the table with the setup. I've had the cam in my car for 2 years now and i've been thoroughly impressed with it.

I am also running the 231/237 and PP 5.3 stage 2 heads. I dyon'd at 403/392 through a 9" rear/4.11's/locker/35 spline axles. I didn't really tune it since I was only getting 3 pulls. I was still running a tad lean at like 13.1 up top. I edited the pcm enough to get me over 400 but probably left quite a bit in it.
I'm running consistent 12.3's@116 (and more if the weather is colder like 117 and change) with my crappy 1.92 60's. These times are on M/T radials and skinnies (but in (90+ heat and 100% humidity). It is a rough estimate. I am sure it is good for way more than I'm getting out of it.
