Thanks Dave,
You may never find the turd that went through the cylinders but check in the intake and exhaust. I hope the left bank is not hurt any worse than what you already found on the right bank. A little solvent poured behind the valves will quickly check for bent valves. A new 540 or 572 would sure test all your suspension modifications. The 540 combo has been refined to a volumetric efficiency level that pump gas yields 700+ flywheel HP.
