318 or 383 What to do...

It's kind of funny I bought the 383 out of the junkyard in 1993.Irebuilt it in 1993 and again in 2012.It has been in several cars I have owned over the years so my buddies call it the ***** motor.I have had it in a 1966 Charger,1980 Volarie,1967 Coronet,1968 Coronet,69 A12 Road Runner,and a 68 GTS.And it all most made it in my 1970 Road Runner but it was a survivor and I just could not do it.So maybe the Duster will be lucky #7....
