Julian, all blocks have a 4" bore as standard and both 302w and clevo had a 3" stroke. 351 clev has a 3.5" stroke.
Since the 302 clevo was only made in Aust it used long 6" conrods(302 and 351C Blocks are the same). 302C uses 58-60cc Closed chamber heads with 2V valve and port sizes, these are a sought after item in the U.S.
Essentially you could get a set of 4V closed chamber heads and bolt them on to a 302 Clevo and you virtually have a boss 302 with a more favourable Rod/Stroke ratio, minus 4 bolt mains and screw in welsh plugs. This would be highly impractical these days.
