292 head on a 250? What would this do?


Yeah, same head on both the 292 and 250, until they introduced the integrated head on the 1975 250s. The first version of the Monojet integrated head was used in 1975 and 1976, then the second version was used in 1977 and 1978 (this is the version my Camaro has), and then the Varajet 2bbl integrated head was used on 250 trucks into the '80s. The Camaro and Nova were the last two passenger cars with an inline 6 in 1979, and for that year they used the non-integrated head that the 292 trucks used.

1977 to 1978 Monojet integrated head:




Later Varajet integrated head:
