Don’t be ashamed, almost everyone does it.

MJ That combo will have never have any HP taken off of it. To many fast ones and too many A an B cars that they will run against in eliminations. It's to bad that is a tough HP rating.

I thought by now one of the fast 396 cars would have hit the 1.20 trigger. I believe it will only be a matter of time. To many of them and again there are a lot of fast A an B cars. I was hoping that John or Scott would play in A or B for a while. The AA has a tough index. How fast do you think the 2015 COPO's. I was hoping to find out at the baby Gators Barry

Barry, I am sure you are correct. I can lead a horse to water,.....but I can’t make them drink.....

Would I be off base if I believe the best 1969 396/375 Camaros that run aluminum heads and are able to run better than -1.20 (and they can) are making north of 700 HP?
Do the math.

No, I know a certain A/S that ran 136 @ Pomona (1000) feet, it didn't make close to 700 HP. What helps a 375/396 is how it carries the power past peak, average HP.

[Frank Castros]

HP factor; 405 with aluminum heads
8.5 lbs in B/SA = 3,442.5 + 170 = 3,612.50
11.25 index - 1.4 = 9.85

The Elapsed Time (ET) Method
This method uses the vehicle weight and the elapsed time (ET) to finish a quarter mile (402.3 meters) on the formula of Horsepower = Weight (ET/5.825)3.

747 horsepower.

9.29 @ 142.24 @ 3600 how much power using your formula?

[Frank Castros]

Approximately 850.

While vehicle aerodynamics can cause this number to go up or down I think a good middle ground is 710 HP. With track weather BP=29.92 VP=0 Temp=60
