Nice run
Mercury. The closer runs are always the most fun ones

. You seem to be a good driver.
A lightly modded late 80's LX 5.0 with a good driver is no doubt AT LEAST in the low 14s so you either gotta be in the very high 13s or very low 14s (BTW what is your best time?).
If the guy chirped his tires in 3rd, I'd guess that was a manual and not auto.
