What's the slowest car you've raced in the 1/4 ?

At New England Dragway the cutoff is 19.99 sec . in competition . No cutoff in time trials . We won a bracket bash with a '66 Coronet , /6 , auto , street tires . 19.98 seconds @ 64 mph going into 3rd gear @ 1000 ft. Went 5 rounds with an average r.t. of .016 seconds . Lots of opponents red lighted . lmao !
