My son's 385 is only around 550HP. He has a best of 1.36, 60 foot and 6.36, 1/8 mile. He ran 10.22/131 in Topeka. His truck is 2850 lbs with him in it. That's with 4.86 rear and 13.5 x 29.5 tires.
The truck is 59% front and 41% rear. Only 5 gallon fuel cell and12 volt red top battery in the back of the bed.
We are switching to 5.14's and 13.5/31 tires. Our local track is usually a little iffy,so just putting a little more rubber under it.
