I swaped a 318 to a 69 RR383HP in a 67 satellit and it was worth it to me, it cost me a total of 1800 bucks and that was with selling the 318 for 600 bucks because it only had 4000 miles (reman) BUT the Satellite is a bigger car. I would put a 360 in because of weight issues and the potential overheating. Either way it will cost you some cash but with the SB you can keep your trannie
