http://www.MuscleCarOfTheWeek.com - This week, we have a special car for Mopar fans from the Brothers Collection. This is the very first 1969 Plymouth Road Runner A12 446 Pack ever built! This was the pilot car used by Chrysler to promote the A 12 Roadrunner package, and it has been called the "Wayward Beeper". Its significant history is bolstered by an appearance in Super Stock Magazine, where it was tested and tuned by legendary speed-shifter Ronnie Sox. This car features the 390 hp 440 V8 with 3 2 barrel carburetors, and A833 four-speed transmission, 4.10:1 rear gears, and a stripped-down interior. This very car has gone 12.91 seconds in the quarter mile, leading Chrysler to call it the fastest A12 ever built!
