Previous best was a 12.65 @ 110.
Over the last few weeks, I've made the following changes to my 331 combo:
- 65mm TB to 75mm TB
- GT-40 Intake to Trick Flow Track Heat Intake
- Increased compression from 9.2:1 to 10.0:1 via head milling (both intake side and bottom of heads to maintain port allignment).
- Steeda #19 cam to Anderson N-41 cam
With these changes, I ran a
12.24 @
113.97 on BFG drag radials with a 1.87 60' time at Norwalk Raceway Park this past Friday. Shifts were right around 6000 on the stock tach.
All in all, I'm very happy with my combo and the results. The intake and cam changes made a huge difference in how the engine continues to make power in the upper RPM band. With my old combo, the power would just fall off dramatically after 5000. Now, the car pulls hard through 6000.
A Big Thanks to Mike for letting me borrow his truck so that I could pull my car up to Norwalk.
