Welcome to the forum and cool car mike! I had a 69 torino fastback 428,4spd, r code drag pack. Love those cars. I personally like a restomod vs all original resto. To me, headers, dizzy, cam, intake, carb, etc is all Bolt on. It can be changed back if needed. Nothing wrong with personalizing your torino as you see fit. Are you going for a driver? Street strip? Compression will depend on the fuel you are willing to run. Some of the guys here run big squeeze with a big cam too bleed off compression. Maybe get a list of your wants and requirements for the car, then get a budget in mind and let the members here help. Great group if guys here and tons of knowledge on tap!
