When ET and MPH Are Not a Match?

Back in the day my 3680 lb BBC camaro ran 12.26@108 first time out, we started the day at a 12.75. so tuning and tire pressure and 13 passes later we found half a second. Next trip to the track, i had swapped cam and carb, and gears from 4.10 to 4.56 we ran 12.02 @112 .
