ThermoQuad 9811S - Electric Choke

Do you happen to remember the CFM of the one he has listed. I'm going to send you a PM RRR.

According to this site it has the smaller 1 3/8 primary's and has an EGR vacuum source.

It's a good carb model. I just sold a ford 460 Thermo-quad with electric choke that had the smaller primary's also.
