Ok, everyone had a dig at the forum moderator...

CGR, note that this is an inverted engine install and while I know that 2C would still work fine in this case, I would personally take a 4C- either 72A or 82A. Ok someone is going to say they have an inverted 2c that runs fine. Just that I wouldnt put in a 2C inverted.
Wish I could come over and raid your engine drawer Campgems
