cam question
The cross ram intake is a major tuning problem. If you pull that intake off and put a Super Victor on there with a Dominator carb you'll probably pick up 100+ hp. That seems like a good cam for a big engine with good heads and a Dominator carb. I have no idea why it doesn't work with the cross ram other than the fact that cross ram intakes don't flow very well.
I do not know how the Stock guys get the MW cars to run as fast as they do. I guess they just work on them for hours and hours. I've run MW engines on the dyno before and they have all been complete dogs. We always see huge power increases when we ditch the cross ram intake and install a good single 4bbl intake.
