Cam is my design. All I will tell you is it pulls hard, and engine has 10" vacuum at 900 idle.
Headers are our std dyno headers 1 5/8 to 1 3/4 step, like a TTI, w 3" collector
Heads are the CNC with very little hand work. If I spend more time with the hand blending they flow about 10-13cfm more. These flow 300/224cfm at .550"
