LIFT.?!
What? Who does that?
I have never heard of anyone here mention anything like that-but I haven't bothered with the race & big block threads or forums either (have little money/no track).

I thought only the exotic racers got .7 lift.

I could be wrong, but that seems funky. I sure hope someone clears that up.
