Post Your 13 Second Combos

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.
 
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.

Nice. I have similar results on a previous combo that I'll post in a bit.
 
my old 68 Charger R/T
440 Magnum 727/Tf 3.55:1 gears
way back when in HS 1975-76-77-ish,
104 octane gas from Tognotti's Auto World
pretty much stock, Offy 360* alum. intake, new 2-1/4" Trust Turbo exhaust,
just a few tuning tricks, lighter distributor advance springs
better plug wires, hotter coil, a little colder plug
changed the metering rods & acc. pump setting in the AVS Carter
Polyglass GT N50-15's & g 70 15's on the front
worn out old shocks on the front, lots of lift
Gabriel Air Riders on the back, 10-15#'s of air
leaving just a few hundred rpm of idle, floor it hook & book
Sacramento Raceway Wed. nights grudge drags in HS
13.90-ish @ 101-102 IIRC on cool nights
it was faster @ Baylands/Fremont & Sear Point,
better air, better tracks mid 13.80's same 101-102 mph

won a few cheap *** plastic trophies with it, consistent as hell
it was my slowest car, at the time
but I could drive it from Garden Valley to Sacramento
race all night, 5-6-7 passes a couple test passes
& back on a tank of gas, with 3 or 4 friends going with me

same car ran mid 9's a few years later
with 2 Holley 600's on a 513ci stroker, 4200 stall, 5.13:1 gears etc.

Now I have a 4.10 gear, so hoping for 12s. Also have Viking double adjustable front shocks and 3 way adjustable CEE-2730 rear shocks. Also Promax is adding jetable metering plates to the outboard carbs and their advanced design center carb metering block, fuel lines.

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
