Should be a straight away swap, as far as I know.

ccc was not just a cali thing man

ccc was caled est early on form about 80 to 83 and then esc later on

it is on the federal trucks too


you need non ccc HEI

otherwise youre good to go


o reilly auto and such have the 77 style remanufactured q jets for 130 bucks btw core is 50
but the choke is divorced on them


once you swap to non ccc carb and hei then you dont need any of the ccc harness or sensors or any of it

can pull it out, its a separate harness from everything else

Kooll thanks for the info

And you MIGHT be best off pulling the system complete, there might be folks in CA that could use it. No choice for them (if emissions inspected) unless they want to go even newer.

pulling it off complete is what i explained above, the carb and hei are really about it, other than knock sensor and map and 02 and tvs switches in therm housing

thats virtually it


good luck

Man I'm telling ya, all these guys with CA trucks are telling you something: CCC was a CA truck only thing. I know you say you've seen it otherwise, but so far the only trucks *proven* with it on them are from CA.

Post up a CCC sticker that doesn't say "CA" on it and I'll eat my words. EST/ESC was a standalone system for the *trucks*, and all non-CCC 305's got it. My neighbor had an ESC/EST K5 from 1981, and it didn't use any of that other stuff, just knock, distributor, and the ESC/EST computer. So did my '83.

1985CA JPG's here spell it out. http://dyeager535.topcities.com/emissions/index.html There is no diff pressure sensor in an ESC/EST truck application.

The 1983 305 sticker shows that the ESC/EST standalone system (used on ALL the 305's in at least the '81+ non-CCC trucks) doesn't use a diff pressure sensor.

At least now we know that CCC was used as far back as 1984 in CA on trucks.

And as an edit, I used my own advice and checked the brochures page. Learned something myself there...3 different 305's in '81, surprised the heck out of me. So not all 305's had ESC. This right here should also help you understand that CA only had CCC:

http://brochures.slosh.com/1981/blazer4.jpg Notice that ESC and high compression were only coupled together? Note also that engine was NOT available in CA, and only the 4 barrel NON-high compression (non-ESC) engine was?

If I could read any of the other years fine print we could discern some more, but I can't. It*looks* like in '85 the 305 wasn't even offered in CA, only the 350. But again, I can't read it enough to be certain.
