Holley list #6212

[1Fast340]

A couple questions about the old 800cfm doublepumper Spreadbores.

Will meteringblocks and bowls from a newer 4150 style carb work on an old 6212 holley?
Or is there a bunch of holes that wont match?

Would a 4150style E85 conversionkit be in the ballpark to work on one of them carbs (with the newer style 4150bowls ofcourse)

Oddball questions i know.

Not interchangeable. Pump discharge passage hole is different in the m/block & I think the f/bowls are also different.
