I was pretty sure the 32 tall tires and the 4.56 gear was a good combo to use for both 1/4 and 1/8 worked well years ago with my 69 Coronet but only a 440 engine 7.10 ET in the 1/8.
After looking back that converter was built by Continental several years ago.
I did have an issue toward the end of last season with the trans shifting from 1 - 2 real fast. {have the air shifter shifting the car by RPM}
{I need to get in the habit of making more complete notes in the log book}
I Adjusted the front band and changed the fluid seemed to fix the problem. This may still be and issue, now more than ever do I need to see if I can recall the run. could be the direct clutch pack is going away.
I'll know more today.
