Best intake for a Thermoquad?!

No doubt! It's the way to go.

A lot of TQ's here so suffer from that issue. Though Long Island is a little more temperate than the middle of the country, the carbs still suffer.

The only. Holley Spreadbore I ran was the short lives 4010/4011 carb. Not a bad carb, not a great carb. Worked well for a replacement unit.
