3700 lbs .. you need to lose weight.. thats the cheapest way to cut times .. take the steel braces out of the bumpers .. every 100 lbs is worth a 10th i think .. 1.85 is a decent 60 footer but 1.6 or so will amplify to about twice on the top end .. speed is good for your times so you def have good top end .. in other words you mite run 7.8 and only pic up 3 or 4 mph ..
