New PB - 10.81@128 1.44 60 foot
We had a cool day here in S. Fla and the track was open so Theofel, Justasheet and I all hit the track and left with new PB's.
I ran 4 times, two 1.44 60 foots in a row though I missed 3rd the first time. This run was a hot lap and an identical 1.44 60. I launched at 6746 rpm and the track held twice.
Enough beating on my daily driver - stock OE clutch, 61,869 miles and 466 drag strip runs, I didn't go back for a 10.7 slip.
DA was -581 per Drag Times and we had a stiff 25 mph head wind due to the cold front that came through last night.
With the AFR 205 heads I dyno'd at 472/414.
We had a fun time tuning Justasheet to get him his first 10 second slip, but I'll leave that for his post which I'm sure will be following shortly.
Here's the video:

Pretty sweet Joe, congrats. That launch sounds so nasty. It certainly sounds like you've got your launch technique back with back to back 1.44s. Congrats!

1.44s?! 
I think that might very well be the absolute BEST sixty foot time out of a stock ('non Z06/non ZR1' but maybe still including those as well?) Corvette clutch in the history of time! 
At least among stock cubic inch NA applications I would think.
Car sounds GREAT too, congrats Joe.

Yea can you believe it's the OE clutch...60,000 miles bumper to bumper traffic. That has to be some sort of record!
Here's the slips to show it. Two in a row.
Here's the video. I blew third. I know better than the look at the board, every time I see a good 60 it throws off my rhythm.

It does show that it really is possible with the right combo/driving/track prep, I thought for sure that 1.49 or maybe 1.48 was going to remain the lower limit on the stock LS2/LS3/LS7 clutch but apparently it's not. Go for it man.

My first clean run in the car (2nd run in the car when new) was a 1.964 60 foot on my way to a 12.970@109.98. I have learned a few things (and made a few mods) in the last 6 years in this car.

Thanks. That was only my 465 and 466'th launches on that clutch. So it did take me a few times to get there.

But drag radials getting mounted on some C5Z front wheels this Tuesday, and cam going in next week! Hope to get close to your 1/4 times, but gonna have to learn all over how to launch the car!
In any case, great work man!

What's wrong with your exhaust? Or did you get something new?
