SS/H=9.00 1969 R-code cold air 428CJ, factored to 360hp Fastbacks were 9.09 lb/hp, Coupe (Allie IIRC) was 9.03 lb/hp, 22 lb lighter but the weight savings was off the rear, and aero wasnt quite as good so probably a wash. Most ran the Fastback cuz it looked more "racy", kinda like chrome valve covers make your car faster. SS/I=9.50 1969 Q-code flat hood / warm air 428CJ, factored to 340hp. |

Lightweight Fastbacks? Do you mean the original factory race cars? What is a Qcode? A 4V? Re the SS/J Cobra - Was that a Shelby AC Cobra....or a Shelby Mustang Cobra 500? Last edited by Rat Patrol; 10-02-2021 at 06:24 PM. |

Originally, Ford wanted these cars to run SS/F=9.50 class at 1968 Pomona so 3184/335=9.50 exactly for the "135" cars, vs 3266/335=9.75 for the normal 428CJ fastback. Ford was trying to give them every weight advantage they could. After factoring to 360hp before 68 Pomona, the cars ended up as 3184/360=8.82, in the SS/E=8.70 class for 1968 Superstock and 3266/360= 9.07, in C/S=9.00 class for 1968 stock "normal" 428CJs So, "lightweight" just means the Shipping Weight was 82 lb lighter than a "normal" 68 Fastback Mustang, so they ended up running in the same Superstock class but just 82 lb lighter. Convoluted story. There's only ONE 428CJ engine, "officially", all factory rated at 335hp. The R-code had a cold air hood & scoop, so NHRA factored it to 360hp. In 1969, the Q-code appeared with a flat hood, getting warmer underhood air. That was factored by NHRA to 340hp. So you could change hoods & run the car in 2 different classes, as many often did. * To further confuse THAT, in 1968, all Mustangs were R-codes, cold air, factored to 360hp. But in 1968, all Fairlannes (and Cyclones if any) were also "called" R-codes, but had flat hoods / warm air, but still factored at 360hp by NHRA, a full class disadvantage so I don't think anybody ran one. The 1969 Cobra is just a Fairlane - kind of Ford's answer to the Road Runner - a cheap grocery getter except for the powertrain. At Fairlane Cobra, 428CJ R-code scoop 3600/360=10.00 W/P Or Fairlane Cobra, 428CJ Q-code flat hood 3600/340=10.59 That would be a really heavy Cobra AC Roadster!

But the car doesnt fit class - not even close. The Fairlane 500 Convert fits D/SA=9.00: 3688/410=9.00 exactly with 427/410hp-4v If swapped to the next engine down, the car is now too heavy: H/SA=11.00 3670/320=11.47 with 390/320hp-GT So it can't be that car, unless NHRA let them swap a GTO engine in there LOL. Here's 4 possibilities, but nobody seems able to hunt down the car: 10.18 dick simon 67 fair2ds 390gt320-4v 10.11 dick simon 67 mustang2cv 390gt320-4v 10.49 dick simon 67 fairlane GTA 390gt320-4v 10.25 dick simon 67 Big Ford Ranch Wagon 427mr410-4v |
