And you are right, its not 457/410 its technically 456.84/409.86 but I rounded up. Oh and these numbers were also after about 6 dyno pulls getting the tune right, through 2 chamber mufflers vs straight throughs, AND he stopped the pull short. I think with a few changes and 1.7 RRs the car has 470rwhp in it.

And before anyone says anything those are not my wheels. They are my g/f's Mach 1 wheels. My black 03 Cobra wheels were on her car because we had just taken her car to the track and my wheels have DRs on them.

Looks like the dyno was generous...Do you have any track times on your car??

Yeah, no.
And there's no way you're gonna make a legit 457 to the wheels with an e-cam and stock heads.
It's almost an insult to come on here and try to play that off. I mean you're saying your 331 with a small cam and stock FORD 302 HEADS makes the same or slightly MORE hp than the baddest cam-only LS1 setups. And the cam-only LS1 cars that put down numbers like that do it with 346 ci, more compression, much bigger cams, and heads that are SICK compared to oem 302w heads.
Sorry...If anything your dyno tuner gave you some overly inflated numbers to make you feel happy about your car and his tune.
