Hey to all, I registered a year ago, but got consumed by " life necesseties"......I have a 66 Toronado. Came from California, motor is a pooch... Want to bring it back to life.. Should I go for the 425 rebuild or the 455? Have heard the 425 is more expensive... Don't care about originality, have many "aftermarket add-ons" ...Just want a good runnin /tire smoker....Any suggestions?
