Since we just missed the LTx shootout we might make this one.
One request, put the head rules / weight penalty and trans rules / weight penalty from outlaw in power adder and Heads up N/A also, hell even up the weights if you want, just wanna compete in something other than outlaw for a full interior 3700lb street car...

Mine around 300cfm and most ported stockers 280-295.

That's what everyone thinks. On a 4.030" bore they flowed 339cfm. There are guys out there with 23* that are close to that. That's why it's not that much of an advantage on the small bore. I just can't seem to convince anyone of that. Besides dragging around 600+ extra pounds kinda negates that. I appreciate the thought though and anything you'd be willing to do is helpful.
