Reference the lump port conversion: Are you saying the removal of the intake port restrictions alone are a waste of time for a street driven engine that will only see 5-6K occasionally? How about reducing the size of those things a bit. They sure look like they choke the crap out of these engines. No offense, I'm just trying to get the best I can out of this engine without re-inventing the wheel. I know a lot of you guys have been down this road many more times than I'll ever be, and 250 HP would totally do the trick for me.
