Hai all, I'm trying to find out a bit of info on my block, to make the build a little easier. From what I've been told there is a difference between a GN and EN Subaru block, and I haven't a damn clue what they're on about. Someone care to share what the difference is? Also I was wondering if anyone (namely you Rossco) has the ability to find out anything about the block from the engine number. All I've got is 480754. Any info would be pretty helpful.

Cheers, Alex.
