Actually to clearify a little on the description of the Super bird and Daytonas,
The Superbird and Dodge Daytona were both one year wonders, the Charger Daytona was produced only in 69, while the Superbird was produced only in 1970, soley for the purpose of bringing Richard Petty back from the Ford Stable. In 1969, if you wanted to run a Car in a Nascar event your Manufactuers vehicle had to have a street fleet of 500 or more cars, Dodges first attempt at a more aerodynamic car was the 1969 Charger 500, this Charger had a rear window plug that fit into the recessed aera of the back window and got a 68 Coronet Grille, this car failed to meet Mopars expectations, and they soon went to design the Daytona. The Daytona was fitted with a Steel, not fiberglass front nose cone to improve its aero dynamics, and recieved the same rear windo plug as the 500, Now during testing the most succesful wing was only about a foot or soo off of the decklid of the car, but this would not allow the truck to be opened(a required feature for a street car) so the wing was made to its size you would see it now. This gave the car an amazing amout of downforce, that combined with a HEMI and its great aero set up produced the first stock car to run a 200 MPH on a closed course. The record was set by Buddy Baker at Alabama Motor Speedway, now known as Talladega Super Speedway. While Productions # are not completely known, at least 500 of each had to be built to comply, so we can assume at least 500 were built in 69. The only available motors were the 375 horse 440 and the mighty 426 HEMI. Rumors of a 1970 Daytona have been circulating, but are unconfirmable. Also Mopar did have plans to produce a 71 Daytona, but in 71 Nascar outlawed the Winged wonders and Mopar dropped the plan. As for performance, the only 1/4 mile time for a Daytona I know of is a 13.92@104 MPH, and that car was a HEMI
Now for the super bird
The Super bird was a 1970 offering designed to win Petty back to plymouth, as in 69 when he did not receive a daytona he defected to Ford. Plymouth picked up where Dodge had left off, the super bird recieved an updated nose cone, to provide better aero, and a new style wing, again whcih gave more downforce than on the Daytona. In 1970 Nascar upped the homogilazation rules and required 1500 of a car to be street built to comply to race, so plymouth quickly forcasted 1,850 units. With the superbird also came 70 Dodge Coronet fenders and hood components. The motors available in this car were the same as its Daytona counter part, however plymouth included the 440 six barrel(Six Pack on dodge cars) to the lineup of available engines. This car would win Petty back to Plymouth in 1970. Even though the Superbirds had the technical advantage, Bobby Isaac would win the 1970 Nascar Grand National series in a 69 Daytona. Like its Daytona brother the Superbird had plans to go on sale again in 1971 but, again Nascar had outlawed the winged cars in 1971 and they dropped the plans. As for performance, the times that i know of are, 14.26@103 for the Six Barrell 440, and 13.50@105 for the HEMI.
On a side note, in 71 you could legaly run a Winged Super Bird or Daytona, but Nascar mandated that you would have to run a 305 CI motor, one driver took that challenge and in 71 he drove the Bobby Allison #22 dodge to 7th place in a 305 powerd 69 Daytona.
🤬 Thanks for reminding me that **** of a company owns Chrysler.
