Thread: Which Carb to Choose

Tweet

A double pumper and auto trans on the street is a poor combination as the secondaries will tip in too quick when you mash the throttle and you will experience a lot of bog. I would recommend a 650 vacuum secondary carb of your choice.

I would have to disagree on a healthy street big block with a decent cam, Ive been very sucessful running a mechanical secondary carb that always had the throttle response quicker and more overall power than a similar vac secondary cabr. With that being said beased on the basically stock small block, yes the only way to go is small vacuum seconday style Holley or even better yet I like a QJ.
