Hello, Does anyone know what the stock rocker ratio is for a 383? Do the stock rockers have the same ratio for intake and exhaust? And last, is it possible to get a rough idea what the lift is of an installed cam with hydraulic lifters by reading the lift at the pushrod end of the rocker with a dial indicator? I can not reach the valve end of the rockers with my dial indicator stand. Any help will be appreciated.
