circle track engine builders been doing 2 bbl builds for decades it ant nuttun new and 1 hp per ci ant nearly as hard to reach as some of yall acting like, its been done, it ant rocket surgery!! go check out some stock class's at some them dirt tracks and you see what im say'in!
You are right it is easy to do with a 500cfm Holley 2bbl and decent intake. A stock 318 2bbl and intake are a far cry from that though. It will be interesting to see what work around they come up with.
