Oops I missed that one.
The 168-170-108 cam was 53 and older PG, 55 and older stick.
For 54 up PG and 56up stick I show Clevite 229-1252 at
244-244 ADVERTISED duration, again those vary all over
185-185 duration at .050 lobe, a more consistent spec
109 LSA
.400 int .400 exh gross lift
So it looks like at the time of the Vette (53-54), the Vette cam was quite a bit bigger than the vanilla 235 cam.
But, the base 235 cam got bigger in a few years anyway, and by the late 50s was near as big as the Blue Flame Vette cam.
Good catch, I am still learning stovebolts!
