anybody runnin barry grant?

Im lookin at a carb for a stroker with a 4 speed. Id like to get an HP but im puttin money in other places. Im wondering if anybody is runnin a 750 speed demon with mechanical secondaries(p/n 1402010). Ive heard good and bad from people, but nobody has actually had one. Any problems? Im lookin for a good street/strip carb.
