Here is a link to the AVS2 650 cfm,electric choke,standard finish(not shiny):

The manual choke version is about $30 less,it might work with the OE choke thermostat,but electric would be a good replacement IMO.

We just put one on an Olds 350,replacing the same that had a manual choke.(The manual version can not be retro fitted with an electric choke like the AFB Performer series)
