completely agree with you on the header sizing.
I am still suprised how much of a curve there is in the tq, although they are nice numbers, expecially considering the mustang dyno.

Hope this helps,

Had you had the opportunity to check one off your own combo's that low and look at the TQ curve I will bet the "hump" is even higher. Im going to get with Bob today and see if he can post the gragh differently.
Thanks,

Anyone want to buy a good used roll back? I've personally blown four tires on it so far... Bob

Sorry to bring up an old thread but would this combination pass CA smog emissions with some shorty headers? Im thinking about a 402 for my 2003 ECSB z71 Silverado.

Might pass CA emissions just the way it is, but to be safe I would widen the LSA a few degrees on the cam which would reduce overlap helping to clean things up a bit so you have no issues passing....Obviously a perfect combination for what you are considering.

My cam specs are a little smaller than that(232/236) and the car feels awsome! I am headed back to the dyno soon and expect to be over 500

Find another pump gas 402 that makes close to 450-460 RWTQ @ 2900 RPM! (corrected approximation for typical Dyno Jet #'s).

Mine does (close through an a4 anyway)......... but you built it
I still owe you a few things Tony including an updated dyno sheet with the 3.46 gears re-installed, results from a newly installed 150 N2O shot and a video; Lance is working on it as I write this.
Laura took a video of me at Great Lakes dragway, but I ran over the last timing cone, got yelled at over the PA system "guy in the black GTO, learn to drive your damn car!!" and shut the track down for close to 45 minutes
Sorry for the thread hijack. My point is that Tony can put together killer combinations and that's why I chose him for my dream build. Congrats to everyone involved in the build and tune, just outstanding results !!!
