I have had it on the dyno today and it produced 410 RWHP at 6500 rpm and the torque flatlined at 350 footpounds very quickly.

Phil, could you share the details of your engine? Heads, stroke length, compression? I'm planning a large bore stroker small block, based on the new Boss 302 block, whenever it becomes available. My current 331 did 372 RWHP @6100 with 9.25 compression, and on 87 octane pump gas. Torque was 340 ft/lbs @5100RPM. This is with a Holley 650 DP carb.
