I guess the guys racing Chryslers must have been really friendly back in those days. Look at all the races they let the 348's and 409's win.
I copied this from another post. I'm sure it's not a complete list but as you can see the 348's and 409's won plenty of big races...
1960... Junior Johnson wins the Daytona 500
1961... Ned Jarrett wins the Nascar Championship
1961... Frank Saunders wins Super Stock at the Winternationals
1961... Don Nicholson wins Stock Eliminator at the Winternationals
1962... Don Nicholson wins Stock Eliminator at the Winternationals again
1962... Hayden Proffitt wins Stock Eliminator at Indianapolis
1962... Dave Strickler wins SS/S at the US Nationals
62 Winternationals B/Stock Terry Prince 60 348
63 Winternationals A/Stock Strickler/Jenkins 62 409
63 Winternationals L/P Franks Sanders 63 Z-11
63 Winternationals B/FX Dick Harrell 62 409 w/z-11 top
63 AHRA Winternat. S/S Dick Harrell 63 Z-11
63 Summernationals A/FX & Strickler/Jenkins 63 Z-11
Little Eliminator
Also, sometime in the 60's, Wiley Cossey won a Stock Class
at the Summernationals with a 59 El Camino w/348.
Dick Harrell won tons of races with his 61 WZ 409, 62 Z11 409, 63 Z11 409, 64 Nova 409 Z11 and 64 Chevelle Z11, the number is too many to count. I have to ask Valerie Harrell for the exact number but Im sure its over 20, the white 63 was th AHRA winternational Champ
Bryan Teal who purchased Harrells White 63 z11 also won many raceas with that car
Dyno Don also won Stock Eliminator at Indy in 61. His car ran in O/SS,optional
super stock. However, he was later disqualified because he had the new GM valve springs that were not yet approved for use.
