yeah gsf are pretty good for run of the mill parts.
just put in a 1600sp, did have a 1600tp before but the oil leak was getting crazy. my mate bought a 67 bug with a brand new engine in it, he wanted a 1915 cal look screamer, so i took the 1600 off his hands chucked it in the bus and bobs yer uncle. i would like a 2litre plus engine for the bus eventually but funds dont allow right now
