LMFAO!!!!........and this went/ goes on in the "metric industry" too!! When I was young I had a 350 Honda. Don't remember the actual displacement, but it was FAR from 350!!
IIRC those 350s were 323s or something similar,lol.
I had a couple of those and still have, in boxes and bags,a nearly complete SL350 circa 1971, that I've had since about 1973; and am still hoping to reassemble some day,lol. 45 years in storage..........
