I've got a newish to me '69 convertible with a 400 engine, Rochester Quadra-Jet carb and 350 transmission.
I'm not super familiar with Pontiac engines or Rochester carbs and neither is my usual mechanic.
The car runs well but I feel that it is missing alot of get up and go. We've adjusted what we can with the carb and shift points but it feels sluggish around town.

Can anyone recommend a Pontiac and Rochester familiar mechanic in the Orlando area?

Especially on the North side as I am near Sanford.

You might need some different gears in the rear. Do you know what is in there for gears? Do you know what kind of cam?
