suspension/gearing/slicks

[85SBC400]

ok guys, i've got an 85 chevy fullsize shortbed that i'm wanting to set-up to run points next year at our local 1/8th mile track. it has a mild small block 406/stock th350/stock stall/stock gears and suspension.

i want to start working on this thing little at a time from now till the beginning of next season so that i'm ready to go.

what are some things i need to be looking at as far as suspension/gearing/slicks for the truck? stock suspension? what would be a good gearing for the truck for 1/8th mile with some street driving around town, and whats a good size slick to start out with? if i have to tub it i will but i'd like to stick to a size that will fit in the stock space.

would 28-10.5's be fine or should i go with a wider slick like a 28-12.5?

i know there will be testing to do with whatever i choose but i'd like to get somewhat close to where i need to be from the start.

thanks guys.
