That would be great,
thats what I and ever other LS guy runs, and this one race had to change for. all the t56 cars and 275 hate it. I tested alot on them and still under 50% chance no blowing the tires off without a slipper clutch.
That and the new holley intake maybe.

Great time every year. My junk is slow but fun to watch fast stuff from both sides. Even though i prefer domestics i really like to see some of the fast import stuff that you never see run any given weekend. They really come from all over for this event.
