I had this carburetor professionally at http://www.sparkyscarbs.com/ to the specs of my '67 430. My main question is to find out what the original sized metering rods were for this Carburetor. It has a TA112 Cam, stage 1 stainless valves, stock '67 exhaust manifolds with dual 2.5" exhaust. An edelbrock performer intake. Rest is stock. So my goal is to find the stock sized metering rods (primary) and buy those as well as two sizes larger and two sized smaller and have the parts in hand for hot tuning it on a dyno to get the best fuel/air mixture. Any help will be appreciated. Thank you,
The only effective tuning you can do on the dyno is full throttle, which will only require a nice assorment of secondary metering rods. To tune the primary side, it's going to take some street driving under various conditions, varying speed and engine load to determine exactly what the engine likes and wants. If you have the means to measure the main airbleeds, I can supply jets and metering rods that will basically be "plug and play" for what you are doing. It would also be nice to know the size of the idle tubes, idle airbleeds, idle down channel restrictions, and idle bypass air (if used), to help make the jet/rod selection. I will also send the correct power piston spring with the tuning parts.....Cliff
