Still working thru a few details to finalize the engine swap but I made it to the dyno today and it lived.
Pretty happy with the power. It made 475/435 with a very flat torque curve. Corey (tuner) is a more conservative tuner to make the car last rather than peak out. He wants me to add an exhaust crossover. He thinks I'll gain 20-30 ftlbs in the mid range by doing so. Otherwise he says the combo's great with nothing else needed.
