Hey Scott I believe your referring to my wreck, yes Im a firm believer in diapers on any modified drag car, I did actually have one on the challenger but it was placed back to cover minor rear main leak,not covering but only third of the block,gonna cost me dearly to restore the wifes challenger, I had one on my daytona at pinks all out at martin 131 windowed the block, not a drop of oil on the track, every track should make them a requirement!!
