Best et last year was 13.30 @105 with a 2.1 60' with a 4.10 amd stock mag heads.this year it's going 13.10 with a 1.75 60' @101. With a 4.56 and new heads.


Been thinking of making the swap to a m1 or super Vic. If it would pick it up. Car feels way faster then last year, track times don't reflect that tho.

So the Question lies. Would it pick up? Should run good on paper, but I'm a tad disappointed.
