Erich - I'm more familiar with the unblown engines, which don't have the different gear-train housing across the front of the crankcase with the extra gear for the water pump) and they have different cylinder heads, just for starters. The actual unblown crankcases are deeper than the standard (at last you can get easily at the oil pressure adjustment, for example). If you email me on ausevenoz@gmail,com I can send you a sketch with measurements of both crankcases to compare. Remember too that there are different routes of pipes, cables etc, plus extra oil tank on your body's scuttle for the blown type - most of which are explained in Chris' book. Good Luck, Cheers, Bill in Oz
