We spent a year fighting this stuff, next setup has a jesel belt drive and distributor.
The only way we "fixed" it was to put 3.40 gears and shift the thing at 7800 in first gear; turn the cam sync off and let it go out the back door.
Good luck Brian and take your time to get the right parts. No need to try and reinvent the wheel on this one. It is a savings in the long run to wait a little longer and get the right parts.

after reviewing all the logs and trying to determine the specific conditions when the problem happens, we may have found the root cause...and it might not be BS3 or COP related. my ECU is also back at BS3 to determine what made it shutdown...
Hope to know more by the end of the week

Hall effect did not help. ATI made a custom shell for this.

I've had my cam sync off for a long time. It was acting up on the dyno when we first put the car together, we've never turned it back on. I only rev the car to 7500, 3.23 gears?

The sensor I would like switched is the cam sensor, not the crank. I will be trying a few things in the future as I don't believe the box is the problem, but rather the input signals. I have never seen this problem with the LS1 type cam sensor, and I ran mine 1700hp on the dyno without issue. The fact that it ran 205mph points to 1900hp in the car, all without issue at over 9100rpm. Mike Brown had no problem early this year and then something went haywire and the misfire started. He did have contact between the #8 piston and the trigger wheel that surely aggravated the problem, but I don't think it was the main problem. I hate not knowing why something like this happens and will continue to work on the solution.
After talking with Brian (op), it seems his problem is unrelated.

fuel injectors are definately a problem...not 100% sure if they are the source of backfires though...
There is a 20lb/hr variance in the injectors...thats almost the size of a stock fuel injector![Icon Eek](https://ls1tech.com/forums/images/smilies2/icon_eek.gif)
The holes that had the highest flowing injectors may have been so rich the plugs could only intermittantly fire the mixture
