First time running the car...
Well Friday night I ran the Camaro at the drag strip for the first time... Times were about right what I had expected. Here are a few of the slips:
First Run:
2.14 60'
9.30 1/8 ET
77.28 1/8 MPH
14.33 1/4 ET
99.18 1/4 MPH
Second Run:
2.13 60'
9.09 1/8 ET
79.87 1/8 MPH
14.02 1/4 ET
99.49 1/4 MPH
Third Run:
2.27 60'
9.05 1/8 ET
81.14 1/8 MPH
13.88 1/4 ET
99.91 1/4 MPH
All runs were performed with the exhaust cut-out open. Ok, now for the first two runs the car was set up the same, although my shift points were a little different. On the third run I removed the air cleaner and 17" heavy duty flex fan. Also for the third run I played with the carb a little bit, basically making it dump a little more fuel in there.
The car was missing out on the top-end though. Please refer to this thread for more information. After richening up the carb a little bit the missing got worse and on the top of third gear I was losing a noticeable amount of power.
I did a short burnout (hardly any smoke), and for the launch all I did was hold the RPMs at about 1500-1600 and release the brake and floor it. I hooked w/o wheelspin except for the third run (just had a tiny tiny bit on the third run).
So what do yall think? I know I need to correct my fuel problem, and I now know just how bad my stock torque converter is hurting me. And a lil more power wouldn't hurt either......

. Do you have plans to go to a better flowing cylinder head any time soon?

. Do you have plans to go to a better flowing cylinder head any time soon? Oh yeah, the track is 600' above sea level, it was about 84 degrees outside, and I am kinda guessing on this one but around 55% humidity.
