Well I guess I should have googled but I found this on a camaro website....

# The 1967 six-cylinder engines without A.I.R. (Air Injection Reactor, aka smog) were supplied with Rochester 1BV one-barrel carburetors. The exact CFM rating of the 1BV is unknown, but it was approximately 250 CFM.

# 1968 and 1969 six-cylinder engines (the standard 230ci/140hp and the optional 250ci/155hp), received the Rochester "Monojet" (1MV) one-barrel carburetors. Rated at 250 CFM, this was enough to supply ample power to the car while still achieving good gas mileage.


Deucecoupe,, So monojet on a 292?? That sort of explodes those cfm "formulas" like 2xcu"=cfm +/- (that begs for two of em!)
It's so much velocity! Maybe this speaks to the iceing you mentioned in the other thread.
Like you said tho: The proof is in the puddin'. So we'll see!!
