John, we went high tens back in the 80's with really cheap engines. 360 with the standard bore 73" 340 piston, strip Dominator Intake, the 590-312 purple camshaft, we balanced the pistons with a paint scale, home ported J heads, Manley stainless valves, homemade deep pan and a moroso pickup . With a thermoquad carb. High 10's in a all steel and full glass 1971 duster. Do you remember Banana Converters out of Canton, OH? Those were the days...
