Bob,

I've had the BG SpeedDemon 650 cfm with vacuum secondaries on my street car for about three months. All things considered, I like it. I do wish I would have opted for the mechanical secondaries but at the time I also wanted the electric choke option. As things turned out, I ended up eliminating the choke altogether. The choke mechanism did not work well. My car originally had a Holley 750 with vacuum secondaries. It simply flowed too much air for my engine as it was set up. The BG 650 has much better throttle response and just works well on my car. I am impressed with the finish and quality of the unit. My engine is your pretty standard 351C upgraded throughout, closed chamber heads and about 10:1 CR.
