I've seen A LOT of posts about making HP with a 318-So why is it so ???

cams...most would scoff at comps xe 256 and the Darling has always been the xe 268 ever since Dulchich built the 340.Lets compare the two...this is comps own Dyno using a 9:1 350 with Dart heads
That 256 is a much better street cam
