Bad a$$ truck 71, Love the heavy hitters, mine is a 66 lon fleet and with me in it on DOT tire through mufflers and a 200 shot NX plate system just netted me a 9.97 and a9.99 pass both with 1.43 60 ft, all with the stock trailing arms 6 in drop springs and shocks, I do have the full Fatman front with willwood 12 inch brakes all around, stops on a dime. Oh and running a cast headed 489 BBC with the plate- pump gas no bottle ran a 11.18 @ 120 mph
