Bummer! Guess I'll have to hop up the Satty and try it.

two cars, same engine: 440, .030 2266 TRWs approx. 8.5, Comp 292 .501 hyd, 906s, stock stamped rockers, home sumped deep pan, stock iron intake with a Holley 750 vac sec. Neal Chance 11 inch that flashed to around 2500( probably about like a factory high stall).Was in a 71 RR with 3.23s and 28x9 MT ET Drags. Open headers. Went 13.57 at 102. Same engine with an old Torker intake was later installed in a 68 Satellite. 6 pack hood , 3.23s, 2.5 exhaust and turbo mufflers dumping in front of rear axle, 14 inch rallyes with 235/60-14 street tires. 13.24 at 103. A 10 inch GER converter and the aforementioned ET Drags got me into the high 12s, and other little changes along the way ( 750DP, carb spacer, tuning, etc.) further dropped the et but that's for another thread.

Budget almost 13's. Stock mid 70's 318, stock 360 heads, intake T-quad, valve train, .484 Mopar purple, headers, 2 1/2 exh, 4.10, 727, stock converter. 14.0@101 on 245 60 street hockey pucks. The key was to much cam with not enough converter or compression. Adjusting either will mess with traction.

 

[dvw]

Next also almost 13's. High 12's@109. Stock low compression (.125" in the hole aprox) 440. Eddy heads and Performer RPM, 600 Eddy, 484 Mopar purple cam, stock valve train, bargain headers, 3.91, stock torque converter, 245/60 Radial T/A hockey pucks. Again; no converter, big cam or compression allows it to hook on street tires.

Never ran it at the track but my friends had verified 13 second cars

73 Challenger fresh 340 with 280/480 cam and 3500 converter with headers and 3.91 gears
72 Challenger with 440 mild cam and 3.55 gears
71 340 Swinger meticulous build with "race" cam headers and 4 speed with 3.91 gears

my car was targeted at 13 seconds from the Mopar drag book

I hung with those guys all night and regularly won
it usually boiled down to who had the best reaction and didn't go up in smoke

70 Super Bee fresh 1970 9.5:1 383 stock 906 heads with 3 angle valve job, 284/484 cam degreed as per the instructions, torker intake holley 650 with a LOT of mods to get that combo to run right, hooker super comp headers stock converter and 3.55 gears
