I apologize if you took my comments as an attack. Maybe blunt honesty wasn't the right approach. What I read was you want a non factory engine package, everything brand new but the block casting, 600 pound feet at 3200, with a hydraulic cam, pump fuel, and completely dyno tuned. In my experience, that is running with the big boys as far as I'm concerned. As opposed to a "built 440" type build that can be done on the cheap and get an easy 450hp. I get it perfectly. I have personally built more than a few using different suppliers and I'm currently building one that is truly budget.
I'm still interested in seeing both track times and reciepts for these engines. I'd be very (pleasantly) surprised if someone got everything you want, as proven by track times and not dyno sheets, for the amount you're looking to spend.
