Details:

Yes, I recommend this product. They should at least indicate that purchasing the kit without linkage is a big mistake. 1-7/16 throttle bore diameter. Pros: Performs As Stated Very Simple To Work With.

Specs Rochester 2G/2GC small base 2 barrel carburetor: 1-3/32 venture 278 cfm 3.0 Hg pressure drop. Converts 3 small base Rochester 2G/2GC main bodies into Tri-Power setup. Cons: Use Their Linkage. Extended throttle shaft and butterflies for primary carb.

Does not include linkage. Pros: everything I needed. Includes necessary plugs and hardware to re calibrate circuits. Its obvious their linkage must be used, so why sell it with or without.

After a bunch of adjustment and using some lapping compound sanding I got them better but not perfect. Although the kit is sold with or without new linkage, don't purchase it linkage. But that's hot ridding.

When I got them the throttle plates were no where close to being sealed. Part # 91011589 Condition New Brand Speedway Motors Sold Each Details Info Theres nothing cooler than a 3x2 intake on vintage Chevy/Pontiac/Oldsmobile/Cadillac/Buick V8 engine, but good carburetor cores are getting expensive and hard to find. I was impressed. This kit does not include throttle linkage, allowing you to customize the application your specific needs.

New base plates for secondary outboard carbs. Kit includes two brand new throttle body base plates for the secondary carbs, gaskets, jets, power valve, modified piston, idle tubes, plugs, hardware, and shaft butterflies primary carb. Was very pleased.
