No, I actually should have waited to get the carb before posting this. I will update when I get the carb.

Thanks,

Jason

I received the carb today. It is a very nice unit. The date is 534, so it is a service unit.

The "Mystery Motor" List #2687 is listed in Colvin's book as "1963 427/430 HP Manual Trans." Not a lot of other info besides having a #3825 Front Metering Plate and a #3827 Secondary Metering Plate and center hung floats. It would be interesting to take a set of dial calipers and measure the throttle plates and then the Venturi diameter around the boosters. Then we could figure out the exact CFM of these.

Well, it doesn't appear to have center hung floats, but I have found a few other errors in Colvins books too. I'm still glad I bought a complete set anyway.

Definitely side hung floats. I believe the first center hung floats were the Lemans bowls for the Cobra, then the peanut bowls on 65 Chevys. All butterflies are stamped 172. This along with the downleg boosters says 780 to me.
