Your Charger would be cool with a stroker Hemi and should easily run mid 10's with a nice Hemi stoker. But the question is that is your pockets deep enough. Myself I built a mild wedge stroker for my 63 with my stock 440 block as I went with a 4.15 crank for 493 cubes. I knew I would only race once or twice a year as my car is 99% a street car and I really only run it hard at the track. Its run 10.70's so far in full street trim as in fact I have never uncapped it or had race gas in it. Its been in my car driving on the street and raced some since 2011 with no problems at all ever with it. You could build a nice 500 plus wedge stroker and run 10's most likey much cheaper then a Hemi build. But a Hemi build in your charger would be awesome. Good luck what ever you decide. Ron
