I owned an export 1989 Chrysler Fifth Avenue 318CID with a Q jet from the factory. It ran great. Started great. I never had to mess with it.

On a different note, I owned a 1979 LRE. It had a 500 CFM manual choke Edelbrock sitting on an adapter when I bought it. The tire smoke terrorized more than one Mustang GT. I did replace it with TQ 6139 for the TQ "growl".

At the end of the day, pick what fits your needs. There are a few good options.
