I think he is refering to stock convertor there as that seems to be a comp cams number.

...and the first set of numbers,(.495 .503) is the lift with 1.5 rockers, the second set (.528 .537) is with 1.6 rockers. The 112 degrees, is the lobe seperation; just right for computor car. 1600 to 5400 is RPM range of good power, and stk conv means you can use the stock transmission torque-converter without going to a higher stall unit. By the way, that's a pretty healthy cam, performance should be close to a Chev Hot Cam.

.....and the first set of numbers (218 224) is duration at .050" of lift. The second (.495 .503) is valve lift with 1.5 rockers. The second set(.528 .537) is with 1.6 rockers. The 112 degrees is lobe seperation, just right for a computor car. 1600 to 5400 is the RPM range that the cam makes good power. And stk conv means that the cam will work ok with your stock, trans torque-converter, as opposed to needing a high-stall unit. This cam is pretty healthy, and should perform about like a Chev "Hot-Cam". Hope this helps.

I do not want to put in a lesser cam, although the CC 304 may be better.
