I have a freshly built 2.7l with 9.5:1 compression pistons. I currently have zenith 40 tin carbs with 34mm venturi's. The engine runs very well however I stumbled upon a nice set of weber 40 IDA's. I am much more familiar with weber carbs so I purchased them.

What would a good starting point for the following be?

venturis
idle jets
main jets
emulsion tubes
air correction jets

Also, are weber idf jets and vents interchangable with 3BBL IDA's?


Thank you
