Re: which engines used the 30/30 cam and which used the duntov? (garagedweller2)
The 57-63 (283 and 327) engines with a solid lifter cam had the 097 (last 3 numbers of the part number) Duntov cam. This cam had a somewhat lower lift than the 30-30 cam and the lash was set at .012 intake and .018 exhaust. The 30-30 was used in the 64-5 365hp (carb) and 375hp (FI) 327s. The 30-30 came from the fact that BOTH intake and exhaust valves were set at .030.
Just for info, this was also the cam used in the original Z/28 engines (67-69 302).

I'll back up DZAUTO on that........ and the 70-72 LT-1 used another/different solid cam (and I've heard the 327 30/30 and the 097 both called "Duntov")

Only the 097 cam used from '57 to '63 should be referred to as "Duntov".
