You can tell the 308 from the 336 by looking at them, but I have to have them side by side. There's a noticeable difference. You can also check via the dial indicating method at the lifter. Measure full lift and multiply by 1.39 (the rocker ratio) You can also get an idea by when then the motor starts pulling hard. With a 308, the motor begins making good power at about 4500 RPM. With a 336, about 5500.
