Need cam help for 340 Duster

Thanks for your help. This car was a former drag car from 76-82 from Ct. Original 340 survived but missing parts. Want to restore the car to that time period as close as I can and get to the track for occasional runs like musclepalooza or a mopar only day. Other than that, go to Lake George, NY in Sept and go crazy with all the other Mopar guys I met up there. Original owner told me the car had steep gears..513's with an auto tranny with a theroquad and 1 and 7/8 headers. The old photos of the car were just awesome. Have original window sticker and build sheet that survived. Thanks again!
