newbee: Need some sound advised on my 70 "H" code Duster!!!

Welcome to the site and better yet welcome to fatherhood! My 2 cents are that you should only change things that you can change back. If it makes you happy go for it. But if your dad has a strong opinion maybe his 2 cents should be herd and respected. How would you like your son to handle the situation someday...Cool car, I think that orig combo rocks, abody, 340, 4speed, equals big block az kikker!!!!
