Just yet another thing to add: theres gotta be a catch to the edelbrock 7194 cam right lol? It has 300/308 adv duration but 238/246 @.050 with .480/.495 lift and 110 lobe separation and an rpm range of 1500-6500........ Does the big difference between adv duration and @.050 affect anything? It just seems like that big of an rpm range too is very impressive.
