Guess the hp ?
Just for fun, im wondering what Hp/trq you think I'll make on my 07 Z06.
I'm having the engine refreshed after have a lifter eat my cam on my 126k ls7. I'm having a mild top end build, with BTR stage 1 v2 cam, stock heads with new guides, stock intake w k&n filter, Speed engineering 1 and 7/8" headers with custom catted x pipe, bronze trunion upgrade, new wp, oil pump, starter, granitteli sp wires. Just replacing a lot of stuff that because it's got a lot of miles.
I daily drive my car, so I wanted a performance upgrade without a lot of big chop.
so what should I expect ?
btw it's too late to do a stage 2... everyone says they drive like stock too.

I'm thinking about 500whp on the Mustang and 525 on a Dyno Jet.
When I first had my 2007 Z dynoe'd after a H/C/E and ported heads/throttle body/intake on a Dyno Jet, it made 556whp and the drivability was lacking. I then took it to a well known tuner is Victoria, Tx and he baselined the car at 509whp on a Mustang and then tuned it to 535whp and the drivability improved.
A year later i added a MAMO ported MSD intake, NW 103 t-body and 60# injectors and the hp went to 591whp on a sub freezing night.

Any other guesses ? Hopefully I get it back today. They were tuning it yesterday, and changed out the old gas because it wasn't getting to the timing they wanted. I wasn't given any numbers yet at all yet

It made 501 rwhp and 464 trq. ... stock intake manifold and stock intake air filter except k@n. Was hoping for 505 plus, it sounds good and this is on a 91 octane tune, because that's what is available around here .

Seems kind of low with the headers dont you think? I was hoping and dreaming with a mild head port and ported msd could reach 550-575 with that cam.
Hows the drivability, and the sound?
Is it better than the stock cam down low below 2500rpm?
