[Fot] Weber manifolds for GT6

[Scott Janzen]

I run 40 DCOEs on my GT6 with a redline of about 7300, though it could go higher.
The chokes are either 28 or 30 - I tried 32s and lost power.  This engine is usable from 4500-7500.  Below that I can’t give it full throttle.  That’s a function of both cam and carb, but I’m with TeriAnn.  You can get virtually the same power out of a pair of SU’s so I know there’s more carb than is really needed.

I don't pretend to be an expert but wouldn't three 45DCOEs be a tad large for a GT6 engine? Off hand without knowing your engine it seems like three 40DCOEs would do the trick and be more RPM flexible.

From my Weber page:
The largest choke that will work optimally in a 40DCOE is a 34 choke. The smallest choke that will work optimally in a 45DCOE is a 34 choke. While larger chokes are available for 40DCOEs and smaller ones are available for 45DCOEs they will not work as well for this application.  The 42DCOE  only had 28, 30, 32 and 34 chokes available.
