Blueprint 408 carburetor

Eggman,
A lot of nonsense creeping into this thread. Use the 800 AVS2. Bouncing metering rods as described above, as a reason not use the AVS, only shows that the person making the statement doesn't know how to tune these carbs!!!
A 238 @ 050 cam in a 408 isn't going to be that great on idle vacuum for power brakes.
