Oh, and a "308" is a 308 cubic inch iron V8 that Holden manufactured in Aus from about 1959/70 through to about 1998. 4" bore x 3 1/16" stroker. 5 litres or thereabouts. There is also a 253 cubic inch. Smaller bore, same physical block size/stroke.
Probably the most widely manufactured V8 in Aus. Period.
It was superceded by the LS1. Which was nice!
