what's 75 Cal. motor?

[Smokie Joe]

I have a 75 vette motor(not the one in my car).It is suffixed as a Calif. motor.I know that a 1980 vette had a Calif. motor also,it was a 305 cu.in.Can someone explain to me what the difference is with this particular motor?Could it just be an emissions thing?Is it a 350?
Thanks much

Only two motors were offered in 75, both were 350 cu.in the base was a 165 horse and the L82 with 205 horse. You could get both with California emissions trim but only mated to a automatic for Calf. While the rest of the sates could get either with a manual or auto.

Your correct on the 80 california motor being a 305 cu.in, that was the only time a C3 was offered with a 305.

Have you looked at the database here on the CAC site.. http://www.corvetteactioncenter.com/specs/c3/1975/75id.html it may give you more detail on the motor you have.

Thanks WhiteKnight,That gave me all the info that I needed.Looks like it is an l-48.I didn't quite know what to expect.That California is kinda weird.The only thing weirder,is that I'm thinking of moving back there after 35 years !!!!

California emission-suffixed engines had a different vacuum advance unit and centrifugal advance curve in the distributor (which was installed at the engine plant), so they had a unique suffix code from the otherwise-identical Federal engine assemblies. There was no difference between California and Federal engines as they left the engine plant other than the distributor.
