Hoosier's recent thread got me thinking. I went out to my spare room and looked around for my extra carbs. Currently I have a 650 DP which runs fine honestly. I also have a 700 DP which I just can't get my car to like. As Hoosier described, the car bucks and bounces, and doesn't start nearly as easy. I found a 750 Holley with vacuum secondaries. The current 650 and 700 both have manual secondaries.
Performance wise, which might be the better choice? The current 650 DP with manual sec., or getting the 750 w/vacuum sec. rebuilt? I'd love to use a bigger carb, but my past experience with the 700 DP leaves me a little leery to mess with something which is currently running well enough.
