ak_petey 's blazer upgrade - stage 1

[ak_petey]

I was hoping to gather some ideas for my 87blazer.

I would like to spin my tires FASTER through the mud.
Ive contemplated an engine build, doubler kit, or engine modifications but I cannot do them all due to not being mr money bags. So my deal is I want as much wheel spin as possible/effective. I can only choose one option at a time. Ideas?

I currently am running a stock 350 tbi, th 400 tranny, np205 t case, 5:13 gears locked f/r and 39x18 boggers.
