340/S Racer Info

[bennyv_3_8]

I have a 340/s that has some writing on the secondary clutch. I know that the sled was raced and came from a dealership in Northern Illinois named Twait and Buck. On the secondary clutch it is marked in a Black marker which reads:

Dave Swanson South Dakota 2nd Day Zaccrello

Any information on this would be greatly appreciated.

Thanks,

Ben
