What size and make of Drag radials? For sake of discussion I will assume the 390-40-17 M&H's. Here are a couple of tips to lower that 60' time. Get a Hurst Line Lock, it makes the burnout so much easier, and saves on rear end abuse (saves spiders, etc.). Keep air pressure at between 16.5 and 17.5lbs, no lower. Check tire pressure before each run. Let the truck cool a minimum of 30 minutes between runs, 45+ is even better. When ready to make a run, be sure to drive around the water box (don't get the front tires wet) then back into the water. Pull forward slightly, set the brakes, hold the Line Lock, put in 2nd gear, holding the line lock, rev to about 4,000 rpm and dump the clutch, hold the revs at about 5,000-5,500 for a count of 5 seconds, release the line lock, roll forward, put in 1st gear and do a small dry hop (tightens everything in the rear). Stage, and hold revs at between 3,500 and 3,800 for the best launch, smooth off the clutch and smooth down on the throttle....enjoy. 60' time should drop into the 1.70's and ET's will drop into the 12.30's-12.40's. Also remember 100lbs equals 1/10th. Bedcover-120 lbs, tailgate-60lbs, spare tire-90lbs, passenger seat-47 lbs (manual 04, but you'll have to cut the bracket to make it easy), sub-woofer 14 lbs, package tray-10.5 lbs, floormats, wipers another 5lbs.....and its all easy to put back...so no one will know.....that's nearly 350 lbs , so you're looking at a 12.0, with good conditions and track prep.
