My 60fts are a tad better than yours at just 6.0 in the 1/8th.... I am hitting 1.29-1.30 and trying to figure out why I have not broke thru the 6.0 barrier.....Hell my mph is 114-115.5, so your making a little more power than me....Till next season! So far, based on the changes, I am betting 5.90 out of the gate or better...

So yes, your 60fts should be better...1.28 or there abouts...
