Cheatham, thanks for your post and I'd really like to learn more from you. It's very rare to find a dirt track Mopar guy. The track will be tacky and slick, it depends on the night and time of day. Usually the track is maintained well. I'm considering a 360 now but I don't know if the cast crank would hold up. Otherwise I can just start with the 318 and later when I get more money I can buy a stroker crank or a forged 360 crank and have it ground down for 318/340 mains.
