Put some 235/60/15 26" tire on for the track, 20 psi. That will get you approx 6K at the stripe and 110 mph. I run the same combo except home ported j head, low gear set 904, 235/60/15 MT ET street drag radial, 1-2 shift 6K, 2-3 shift 6200. I'm putting IMM LAX heads on this week and will let you know what I run when the change is dialed in. I dri ve 50 miles to the track and chassis setup was the key for better ET.
