Stock 318 2 Barrel Cam Choice

They are.....but they also WORK. There have been many people use them in actual racing circles that have had great success. Could they have chosen something that would have worked "better"? Maybe, but they are a quick go to for that cool sound, plus if the rest of the build suits them they will work!
My short impression'd be that it functions like a bigger cam scavenge-wise, and like a smaller one with an advanced IVC. Which I love tighter LSA's on a lot of the flow-starved stuff I've dealt with. I wasn't puttin' 'em down Dude, just sayin' why I haven't given them much attn.
