LTRs are damn fast, he wil smoke you, I have a 2006 banshee with pipes, filter, reeds and my friends ltr run next to me and is faster on the topend, my gearing is stock and hes as well except he has gone up from 18 to 20s at the rear, which makes the gearing taller. Ported banshee will smoke a LTR on a drag race, a 421 cup will walk over it!!!! But if your not ported and your weight is the same, watch out.
On the track I think the LTRs will be better, great handling and torque.
