Does anyone know what the deifferences are between them? External view looks identical. My experience with aftermarket carbs thus far is limited to Holley, and it has not been pleasant. I can never seem to get those things dialed in so they run well. I don't want to repeat that. I'm considering getting a Carter or Edelbrock for my 64 Skylark 300 (currently has Rochester 4GC). I know Carter built a couple different carbs for the 65 300 motors (3826S, 3827S) so I would imagine it should be easy to tune one to run well (hopefully as good as the stock Rochester?). Instead of scrounging for the right used Carter I could just buy new Edelbrock if it is identical and can be dialed in easily based on how the stock Carter is set up. By the way the reason I want to do this is the Rochester throttle linkage is incompatible with the 4 speed trans I am putting on the car. Several kits are available for Carter/Edelbrock.
Externally a Chevy looks like a Toyota (they both have 4 wheels). :laugh: The easiest way to dial in the e-clone is to replace the engine at the same time with a 327. If you wish to retain the Buick engine, then you might consider changing the idle tubes, the vacuum piston springs, the metering rods, the idle air bleeds, the main air bleeds, the secondary metering jets, and the secondary air valve in the e-clone. If you drive the vehicle when the ambient is below 50 degrees, you may wish to change the choke, or figure on a second cup of coffee after you start the engine, before you move the vehicle (A/T only), unless you purchase one of the manual choke models. If so, you will need to add the choke control inside the passenger compartment. You will also need to replace the throttle linkage and the air cleaner. There are other major differences. In the for what its worth department, Carter build 505 DIFFERENT AFB carburetors. They certainly did not spend all that money on tooling if half a dozen units would do the job. Jon.
Thanks for the info! I guess I won't be buying an Edelbrock. One more question I have is on the throttle linkage though. The Carter's I have looked at recently (not Buick 300 carbs) all have a throttle linkage which looks similar to the Edelbrock and that is one reason I was thinking of buying the Edelbrock. Are you saying the Carters on the 65 Buick 300s have a different linkage then the more common ones you see? Forgive me if it is a stupid question, I've seen several 65 Buick 300s, but never looked close at the linkage, and if it isn't like the common linkage you see on most the Carters floating around it may not be any benifit to me to switch to the Carter.
I have not studied the '64 models, but the '65 linkage has the extension for the switch pitch control, a pad for the dashpot, ball for the throttle all in the right spot. I've had an edelbrock set to do all this stuff, but still had a better running car with a non rebuilt(!) stock carb. :eek2: I like the stock ones! :beer
Each make of vehicle used their own throttle linkage. You will see more bowtie carburetors at swap meets (under than Buick meets) than you will see Buick carburetors. Most of the aftermarket linkage is designed to work on the bowtie, and can sometimes be modified to work with other makes. And there are no stupid questions! Jon.
I'm in need of one of those little linkage extensions for the switch pitch to hook up to. Are they available from some place or only from one of the old carbs??? o No: If someone has one they would part with please let me know :TU:
That is the exact problem I am looking at. I think the answer as best I can figure is they are not available for any Buick carbs. This website has some kits for the chevy carbs, and you could probably modify it to work on Buick: http://www.tvmadeez.com/1406_cam/
