I didn't see that other thread where you were borrowing the Charger for a photo shoot. So ya fooled me as I thought that you were buying one on the cheap.
Stroking the Dart this winter? Great! It'll almost run like my fish did after the change except you won't hook with stock spring location cause it still will run 255's at best - ask Casey. You will really like the difference the 4" arm makes. What crank / rod / piston setup you gonna use?
IMO all SBs need a stroker crank.
