The bigger question I have is.... Can the rest of the valve train handle such a drastic change ?
For instance.... Adding a cam to a LS1 GM V8 isn't as simple as a $400, lol. Its a $400 cam and $400 of other stuff to let you use said $400 cam, lol. Dohc 4 bangers tend to handle up rated cams pretty well, but I doubt their stage4 cam is going to be effective with stock springs, retainers etc.
[MENTION=3178]maperformance[/MENTION] mentioned we have very mild cams since "ECO"boost was still meant for economy and low end torque/response mostly. I've never claimed to be a cam scientist, so... Hopefully someone with a degree in cam-oligy can enlighten us on what some of these cams may or may not do...
