273 commando HELP!!!

You are the Man toolmanmike! I love your in depth chase for a ripping street 273! I admire your attitude about it all. I just had my engine balanced after rod machining and I gasket matched the heads and blended out the transition in the Combustion chamber squelch area... Stock cam. Head milled (Do not have numbers) two + times... Bored .030 and a 600CFM Holley.. Oh stock manifolds & Dual exhaust. I am guessing about 280 HP or so.
