BILLY Thats a good ?
here is what I have found with some testing and playing around.
The 2bbl atomizes and mixes better at low rpm but tends not to have the top end power.
the 4bbl however is just the oposit,ok on the bottom but great on the top end. you will find alot of 2bbl on the small tracks and 4bbl on the bigger tracks, my freind and I both race street stocks in Fallon nv. our cars are pritty much identicle but I run a 4bbl and he runs a 2bbl ,he pulls me comming out of the turn but I pass him at the end of the straight away of our 1/4 ml track, so I hope this helps you out.
