No issues
Carb dropped onto my engine and fired right up. Easy installation no adjustments needed. Did have to by adaptor plate due to using stock spreadbore intake

Performance
Ordered this carb, arrived the next day, bolted it on after installing linkage and air cleaner threaded rod. Fired right up after fuel entered it and I only had to raise the idle slightly as my 72 Pantera has a 351c with a manual gearbox. My old carb had a hesitation and this one’s works awesome.

Make sure all parts are in box before shipping
Some of the parts for the throttle cable connection was not in the box very disappointing
