when i started to read the thread i was like "stock camaro my A$$!!"
a good H/C/I pushrod 5.0 will mop the floor with a stock 2010 SS, but then i read what kind of h/c/i he is running and then it made sense....
That's correct, OP isn't making 302/314 and much less in a mustang dyno. He'd be lucky to put down 270whp or so in a proper dyno, and a lot less in a MD. With a Trickflow top end kit you would've made over 300 and would've likely beat that camaro.
