Your buddy never had a 1970 challenger rt 340 they never made 1 lol
carry on
Shelby Turbo-Charger(non-GLHS), with good tires(not slicks/cheaters), could run 14.80's. Hot Rod mag beat the piss out of 5.0L HO LX(14.6's), 5.0L GT(14.88 BEST ET), 350 IROC Z(14.88 BEST ET). That was an '86 Shelby BTW, when new.
The problem with the Daytonas was the weight went up faster than the advances in the engine/turbo tech, My '88 ShelbyZ weighs as much as My '69 Dart Custom HT w/the 'teener & 4-gear did, not a favorable move. The fact that the exhaust necked-down to 1&7/8" by the side of the fuel tank didn't help.
The '89-'90 5.0L 'stangs with the timing jacked up & the intakes iced-down were doing ~97-98mph in the 1/4, & 13's mid-upper with DOT Quick-times etc. & 3.73's.
My bone-stock ShelbyZ only topped out @88+, so those true, had a long way to go at that point. The Omni & Charger bodies were much lighter, & a way better choice body by 5-600#.
