Power to the ground

[tickets]

I'm working out the traction problems in my '68 c10 lwb 2wd and thought i would try this board for suggestions. I just swapped in a hot 350/350 combo in my truck. I relocated the gas tank to the bed, installed a detroit locker and 4:10's, and i just put on 15.50 micky thomson sportsmans on the back. the tires made a lot of difference but i still smoke 'em off the line and in the upper rpm's of first. What can i do to get the tires stick better? its got coil springs all the way around, all stock. id liketo drop the truck some but not too much 'cause i have headers and exhaust hanging down. Oh yea, its my daily driver.
