I had a similar problem a few years back. Car would run a few good laps then fall way off( 1/2 sec) starting in top of 2nd gear and to the stripe. Then it might not act up again the rest of the night, or might do it 2 or3 times. Tried ice, moving stuff around, finally after two months of guessing I got lucky and swapped out the 6al box. That fixed it. Mine fell off a lot more, but otherwise similar symptoms. With having a spare box, it's a quick possibility to rule out.





Sounds exactly like our problem Don. We are still going to try a different carb and hopefully test Wednesday. We will have our spare 6AL with us and swap if the problem arises. If neither fix the problem then maybe we need to consider a converter change.
