The stock cam is pretty good.

Yes, There is nothing wrong with a stock cam for a stock engine. I ran a 10.83@125 with a stock cam/stock engine. Other racers have gone even faster with the stock cam.

10.6@125@3700+ heavyweight trim on the stock cam back in the day.
Doesn't have much of an rpm window but could make enough power to Crack a few pistons
