What is the BIG difference between flat tappit and roller cams
I was told I was going to get a roller cam in my new 383 stroker engine come to find out this joker put in a Competition cs 268 h 10 high energy hydraulic flat tappet cam.
1st . Is this a good cam
2nd. I was told this cam is 2 steps up from stock is that true ?
3rd . What did I lose by using a flat tappet instead of the the roller?
