Anyone have old Direct Connection or Mopar Performance books or articles?

Specifically trying to find technical information regarding the ins and outs of how the Mopar 305 was built by de-stroking the 340 back in 1970 to qualify to race in the Trans Am series against Mustangs and Camaros (and used once in a winged Dodge during a NASCAR Daytona 500). Interested in identifying the specifics of the rotating assembly (crank, rods, pistons) and cylinder heads. Or if you have a motor, I'd like to look it over. Thank you.
