Hi. I found a great example of an intake manifold I want, but dude won't separate the carb off the top.
......
I'm gonna buy them both to get it. :(
I have less than zero need or desire for the Holley carb and it's looking for a new home. I've been hagglin with dude for three months! and he won't budge an inch, but he finally made me a okay offer. I plan to swap heads in a couple of weeks and I have run out of time. :(

That is a CCC compatible SPREADBORE Holley with a TPS? plug in it. I believe it was advertised as a direct replacement for Camaro-Firebird.

I'm thinkin $50 bucks ISH + free ship. $40+ ship.
Got another idea? Let's make a deal Monty Hall.
I has a PayPal. Anyone interested?
Remotely? I don't own anything with a computer or I'd run it...be badass for some of you rounded line dudes! Whattup my square headlight brethren? Check it out!

I'd imagine only Cali guys would be the least bit interested in that. I think it's more into about 84 though that the CCC came out in Cali trucks. Not positive, it might have been earlier. I know GM started OBD1 in some model cars as early as 78 and it was a C4 system. C4 was Computer Controlled Catalytic Converter, not that the Cat was ECM controlled but that the car was Computer Controlled and it had a Cat Converter. Then the CCC Computer Command Control took over. A bit more enhanced OBD1 system.

Ya, I take it as '81-'89? Looks like it would have swapped on my '87 SS.
I don't know...
There's plenty of those dudes in here.
Carb is said to be in "nice original condition" and I has great price for you! It was VERY expensive new.

50 state GM cars got CCC for the '81 model year through the '90 model Oldsmobile cars, primarily the wagons with 307's. I wonder how that would work without a mixture control solenoid, and I wonder if you could pass visual in CA without one. I have no clue what it's like to be under the scrutiny of an emissions inspection. I don't know of a way to bypass the MCS, and it'd probably run great; it'd just have an SES light. Maybe if you could bypass it or have that parameter tuned out of the PROM...

It maybe different for the older cars now, but in Cali when we did smog insptections if we seen the carb adjusting caps has been broken out, we were to fail that vehicle. UNLESS, it had a record of fail and a smog station broke them out to adjust the carb to make it pass. That carb without the mixture solenoid might be 49 state compliant but not Cali compliant.

I know in somewhere in the late 70's there were some G bodies, wanting to say the Buick Regal and Old Cutless were C4 but the Grand Prix, Bonneville, Malibu and El Camino were not. They had a Cat but not ECM controlled. In short, some models were guniea pigs for the computer controlled cars and some were not. That was in anticipation of the stricter mpg and emissions laws coming into affect because it was not required. It also could have been a fleet average across the board. As in the GM fleet must meet this avg mpg and emmissions, so some models were chosen to bring that fleet average within legal specs. Strange how they did that. But that's why. The good ole US of A gubment working for us.

Yeah, I agree. I don't think this'll fly in the more strictly regulated emissions in California, but it'll be fine elsewhere.

I just looked it up. Not a lot of info on Computer Controlled Catalytic Converter (C4), but it looks like it was around in 79-80, which makes perfect sense about what you said about it being a proto-OBD I testbed since CCC came out the next year. I've never heard of it until now. I knew that Cadillac had that early foray into computer controlled fuel injection in the mid-70's, but that's kinda cool that they took a couple years to prepare for CCC in practice instead of just tossing it out there. A lot of people who still remember CCC hate it, but I think it's really solid. Besides my ECM getting wet that day, it doesn't give me problems, and I'm getting 20-22 MPG on the highway, which it's just a 305, but still. I trust it in New Orleans commute traffic and running down the interstate, and the whole system hasn't let me down once.

That Cadillac Computer Control FI you're talking about only came about for 1 reason, or should I say 1 purpose. Cad had the Infamous 4-6-8 system. Any clue what that is? Better known today as DOD or Displacement on Demand. Though it wasn't seamless and IIRC, it was user selected via switch.

hmmm, I'm not so sure this is true. Or maybe I'm misunderstanding what you're saying.

Cali won't pass **** on visual inspection. It doesn't even matter if it passes all tailpipe emissions. It must also pass all visual inspection too. You can't even pass in Cali if you've removed the Thermac Air Cleaner or drilled holes in your air cleaner. This is when the flip the air cleaner lid came about in sorts. Now it only gets put on right every other year for about 15 minutes to pass inspection, then after that, it goes back on upside down.

Okay, I gotcha. Besides the few nuggets of regulation I've picked up from CA members or former residents, I don't know much about the rules, but I understand now that the visual and functional component go hand in hand. I was postulating later in the post about simply making the Holley work correctly in conjunction with the CCC in an unspecific, emissions-free setting.

Back in those days, there was 49 State Cars and Cali Cars. Not all Cali cars were C4 or even CCC. Just like Fed MPG Requirements, Cali emmissions started out as FLEET wide averages. So if the Feds say an auto manufactuer's must meet this mpg AVERAGE requirement, it was FLEET WIDE. So some models could be gas hogs, then it had to be made up on some more efficient models. So if they wanted to sell this many boat cars with smoggy big blocks, then they had to make this many more econo cars to offset it. This is partially why many manfactures got in bed with foreign companies. Dodge got with Mits, Ford got with Mazda, GM got with Isuzu and even some Toyota. Just slap a Chevy, Dodge or Ford label on one of the *** models, and now they met the mpg requirement of having a FLEET Average of whatever the mpg was to be better than.

The last "carbed" cars were Olds because they were clean enough up to that point without any further changes.
