Hi there,

You have 42mm chokes, and F16 emulsion tube.

A book I have states for Chev V8 of 4949cc with Quad 48 DCOEs (a sidedraught IDA equivalent) to have the following: 40 choke, 165 main, 160 air, F2 emulsion tube, 50 pump jet, closed pump bleed, 55F8 idle jet.

My choice is an F2 tube, I ran an F2 in a 308 V8 but I have since sold the car.
