DB secondary rods are correct. That carb either used 71 or 72 main jets from what I can remember. I use the same carburetor on my own engine, excellent units. It's a completely "stock" unit, no grinder or sanding roll has ever touched it. It is recalibrated for my application, and to date NOTHING we've ever tested against it on the dyno or at the track will outrun it. Believe me they (the dyno shop I use) has tried many times and none of their fancy Holley or Holley clones will make more power or quicker in ET or MPH!
When it comes to rebuilding and setting the carb up keep in mind that this new fuel doesn't have the same formulation as the fuel that carb/engine combo was calibrated with so re-using the stock jets/metering rods may not come up with the best end result. It's also rare to find one of those engines unmodified and ALL of the original emission related components in place and functioning correctly.
Not really a big deal as the carb has an APT system and outfitted with the right parts you can easily dial it in for any application.
I would recommend one of my rebuild kits and if you want more information and tuning parts, etc, call the shop and I can put a custom rebuild kit together for what you are doing.........Cliff
