Yeh, practice is really important.
With practice I've gone from 12.97 to 12.21
And I still need to get better at launching - my best 60' is only 1.85

Not bad, your mph is good for low 11's. Just curious though, how is the car only putting down 440 at the wheels? The trap speed would be right around where it should be for that power, but I am curious on your setup.

Those were the numbers from the dyno I just did a month ago. Unfortunately I got little info on the build/tune when I bought the car. It is a Shirl Dickey 418, so I'm trying to track down some more info on it. What numbers would you expect?

If I was personally doing a 400+ cube motor, I would expect 480rwhp minimum. It really depends on what top end you decide to go with. I wouldn't get too worried over dyno numbers, they are more of a tuning tool than anything. As long as you are having fun with the car, then that is all that matters. My car should be a lot faster than it is, and it would be if I let other people drive it, but I still have a ton of fun with it.

Do you happen to know what intake,heads,headers and cam that your combo is running presently?A 418 is a nice size motor.You should be able to pull so rather hefty HP/TQ numbers with that bad boy.

I'm trying to get the sheet from the dealer, but if memory servers, Absolute Speed stage 2.5 heads, stock ls6 intake with halltech with K&N air filter, cam I dont remember exactly but it is a medium sized aftermarket. Harland sharp pedestal mount rockers. Ill hopefully hear from the dealer in the next couple days.
Also, the ad that ran with the car said 484rwhp. When i had it dyno'd the guy said i had bad carbon buildup and needed to run cleaner through and clean the intake. Possibly robbing me of ~25ish rwhp. Said there is slight detonation at high rpm's. I just ordered a pcv catch can to help with that.
