Here is Fastgraphite04 doing a burnout from a punch OFF IDLE. Full street trim, 20's and 3.55 gears and 85+ degree's outside. With the 6.1 cam, he could only chirp/churn the tires from a standstill punch with his 3.55 gears and 20's. Now he has fun.
Here's another 210x cam truck. Not many folks are familiar with the KRC 210x cam, but it's put a handful of trucks in the 12's n/a. Match the cam with heads and suspension/weight/all bolt ons and it's a 12 sec combo.
