Was there any reason you chose an SC grind?

Do you have any pics on how you installed the fuel pumps?
I thought they were just pistons swapped in but I guess not according to JMA. I bought the car the way it is, the cams were already in. As far as the pumps, one is by the tank and the other runs parallel to the trans mount.

You'd need to bore them out, or use OEM 930 cylinders.

OR, slip in some custom made JE's.
I asked this before in the "911 engine rebuilding" forum. My barrels appear to be factory 3.2's (by part number) while my pistons have a greenish color under the crowns and the only number I found were a single "5" stamped underneath. No one said what pistons these may be. So, I might have a 3.3?
