My dyno numbers I have an 06 gto m-6 with a 402 stroker , fast 102 ,cam 247/251 624/624 on a 114 , electric water pump , harland sharp rockers also with RPS twin clutch with one piece shaft and 3:91 gears oh and slp under pulley and k&n intake and American racing headers 1-7/8. The car put down 496 rwhp and 438 rwtq what do you guys think of those numbers?
My car with with a 408, ported 102, 244 248 612 615, tfs 225's, harland sharp rockers, Ram HD clutch, 342 rear end, power bond pulley, Kooks 1 7/8's headers and a stock water pump made 499 and 469 trq. I would say you are a little low but not alot.
I am going to a electric water pump eventually just have had the money yet. There is a thread about 408's and dyno numbers. It is stickied, check it out.

Who tuned it? What catback? At first glance the numbers seem a tad low, but there are many variables in a setup like this. My 402 started around 445whp and quickly moved to 511whp with some intake/exhaust tweaking. 
That was with a similar sized cam with LS3 intake/heads.

What kind of compression? On paper it looks like a nice setup ... but the results do seem low .... My 402 made 508rwhp/497rwt on a DynoJet with 90/90, 1-3/4's & 215's.
I see alot of "lower" torque numbers with the 102/102. Several threads & postings have mentioned they seem to hurt torque. With the improvements over my 402, I expected to see 525+rwhp and torque numbers close to or just over 500 for your setup.

Could have a little to do with the tune also. Check the tune. Are you running speed density or what? Seems like a strong build so i dnt see why you wouldnt see atleast 505-510 RWHP....
