I recently purchased a holley 4150 HP series carb. 750 cfm and it is a double pumper with mechnical secondaries. A buddy of mine says that you can tune a vacuum secondaries carb for the street easier and that I will be washing down the cylinders with the double pumper? Anyone out there have an opinion on this or any feddback? I have been working hard on a Chevelle restoration and don't want to mess the engine up by having too much carb! Anyway please check out my restoration project at, I have added some forums and you can be one of the first people to post to them. Also dont forget to check out the Car Show Babes forum, there are some nice pictures there already! :hurray:
