This cam has a nice note at idle & is smooth on the valvetrain.
The 543 has great pulling power from 3500rpm to the rev limit.
Very strong torque curve, pulling hard from 2500-5000rpm. 30 ft-lb increase at 4150rpm, it’s a great torque cam in a 107ci kit.
This cam pulls hard all the way to the rev limiter & gives great horsepower figures as well. A very nice cam combination for a big bore kit.
A very nice cam when chasing strong, broad torque 2200-5000rpm
Awesome in a 103ci Twin Cam as well.
