I believe Mike K turns 9000 RPM w/aluminum rods ,aftermarket head & posibly a stock style oil system, but dont qoute me on him having a stock oil pump.
I have turned up to 7500 rpm w/stock rods, heavy TRW pistons & standard volume oil pump,Crane gold aluminum roller rockers 1.70
My rods are side grinded/polished,then shot peened @ ARP rod bolts installed.
Cloyes gear timing set. Chrome Moly push rods.
Standard weight valves,dual springs,solid flat tappet camshaft.
Nothing full race @ all.

Normal RPM was 6000-6500.
