AI H/C track times.....

Good job. 11.5 @118 is a good shake down pass. What size tire do you run (track/street)? The gear will help keep you in the power band. It sounds like it's going into OD, or maybe the converter is only locking after the shift to third? Do you remember the shift points during the pass? It's hard to guess, but the engine got dragged down big time. Definitely get some sort of logging software (Data master should do), and a wide band.
Good luck with the project.

I would try a 4:10, and see how it feels.
I looked up your dyno graph, and it pulled clean past 6500. There was some room for improvement, but thankfully it appears to be tuning and not mechanical. In your other post you mentioned a lean condition in upper rpm range, did you solve that? What injectors are you using?

That car is running great!
I used to run those exact times pretty consistently. Droping my 60ft by 1/10th usually nets me about 1-1.5mph in the 1/8th and the same ET. You will likely find that your car is very sensative to 60ft. Gears should do quite a bit to help your 60ft and back half performance. If you are only crossing at 5200...you are way out of the power band.
I have to agree with what has been posted by the others about gear selection. If this is a "fun car" and not a "daily driver" I would step up to 4.11s. They will put you higher in the power band at the trap. If this car will ever see nitrous, factor that into your gear selection too. 4.11s won't provide much room but will shine on motor.
Good luck wideling down your times. The small changes make the biggest improvements from what I have found.

That car has enough to go low 11's but those last few tenths to go 10's aren't easy ask me I know. Although I haven't had enough time to run my car very much b/c of a new set of twins along with running a new buisness, there is almost no time left to play but I remember 2yrs ago when I ran 11.61@117mph with LE1 heads, 220/230 duration Joe O cam with 3.42's out back. On the first trip to the track also but broke the stock 2 bolt main caps on n2o the same night,(6.60@105mph spinning the little 26x10.5 ET streets) before I got it lined out good so I know it's very doable. Not many people put the time and effort to get these cars down the track quickly. After that I went with LE2's and a CC306, built shortblock with 4bolt mains, flattops and ran 11.20@120mph with 3.42's @3550lbs too. Then the last setup didn't get enough passes (11.09@123mph) before I noticed the oil pressure was low after I grinded on the heads in the car for pushrod clearence and some aluminum got into the engine so I puilled it down. I found the bearings about to spin but nothing too bad. All the parts in good shape but I decided to try a stroker crank while it's down to see what it will run with a little more torque. Good luck Clint

Thanks everyone!
I'm running 30lb svo injectors and have now swapped in a racetronix setup. The car is dipping into the low 12's to high 11's on the afr after about 6k. This is due to previously having to add so much fuel because the stock pump couldn't keep up. Besides a gear change a retune is also next on my list so we can get the afr back on track.
Using the reports from weather.com for that day the DA was about 700-800ft...Not sure on the weight? Probably <3500?? just a guess though
The car is not a DD but I think I may stick with a 3.73 since I'll be putting the bottle on it.
