Ok, guys looking for some input on which compound I should use. I am almost done with my 58 Chevy Apache 3100 truck. 12 point alston cage, alston back half, Profab 9 inch rear end, 5:14 gears. 572 Keith Black BBC- 15:1 J E pistons, Brodix BB2 plus heads, highly ported and flowed, Pro stock tunnel ram and twin dominators. The truck weighs 3,000. The tires size I will be running is 33x16x15. Hoosier makes three compounds to pick from: DO5, DO6, CO7.
