I have a really stout 440 6-bbl I built for my 69 Dart. During the build I purchased my 69 RR pulled the 383 and took it to the Machine shop that I work at part time. The 383 is warmed over ie: cam,intake,slight head work so on. I was curious which engine I should stick where? Both cars are a-833 and 4:10 equipped. Just curious what you all thought I should do?
