Carter Thermoquads ~ 'More General Information'

old thread but worth reviving, question:
the list of "good" solid fuel metered TQ carbs,
why is #6090 not in the list ? It's a factory 400 cid carb,
with the larger 1.5" primaries, 850cfm
how bad can it be ? ...

See post # 16. I've run a 6090s TQ and 72 400 intake on a street HP 383 and loved it. Got 18 mpg highway to boot.
