If you mean, L grind, they were in Evolution engines up to 91. A good cam for sure, but no match for aftermarket stuff. Your 94 Dyna will come to life even more with an Andrews EV-27, which is a very popular bolt-in cam.

Damn good Cam... especially if you do Not care to spin a bunch of RPM's for some little power gain... RPMs have always equated to HP... I use Torque when I ride on the street... We ain't Drag Racing here.... are we???

I took a tour thru the engine plant in Milwaukee in1985 and they were assembling the new evo motors. all the motors are dynoed (not in any bike just the motor)and they were looking for 60 horse power at the crank. some were higher and some were lower than the 60 HP. if a motor was significantly below 60 it was pulled and rebuilt. if it was well above the 60 HP it was pulled and used in police bikes according to the tour guide we had. he was a long time retired HD engineer and he knew his stuff. I asked why there was a difference in HP on the motors and he told me even tho all the parts should be the same they're not. some parts just work together better than others. it was basically the luck of the draw on how a motor would make HP.
