Bunch of Noob question from a Dutchman
Years ago we rebuilt a stock 73 Chrysler 440 reusing pistons since everything was still standard sizes only upgrading the cam and dropped it in my 69 Charger. Ran quite well; in fact, my wife said it was the fastest car she'd ever drove!
I see you're from the Netherlands. My oldest son lives in Hoofdorpp and works at Schiphol as an aircraft technician. We've visited several times and had some great times.
