Hi, I have a 1970 Model S (that's the date on the matching title, although the frame has 1969). Its a basket case for the most part and I am rebuilding it to utilize a Drouin Supercharger. I realize that a late 850 motor is probably a better starting point strength wise, but I don't happen to have one (outside of my fairly stock roadsters). But I do have a set of 850 cylinders and pistons. I was wondering if the 850 cylinders could be used in place of the original 750 cylinders. And yes, I do plan on replacing the main bearings. Any advice would be welcome! Thanks!
