Grounding Kits- People with automatics SWEAR BY THEM. I've got a stick and am an Engineer who likes equations. I haven't found an equation that proves to me the wires do squat. However, the general concensus is that you need to contact Gordgee (site Admin) and buy his 10 wire kit. Supposed to be the best kit on the market.

Level 10- I've heard bad things about them in other posts, no experience with them myself. If you want more info on them, DO A SEARCH! Also, contact Gspot35 if you want to know what you need to do with an auto that's S/C'd. He's pretty much the pioneer (as far as I know) in this arena. I've actually taken a ride in his high 12 sec. G. The poor corvette driver didn't know what hit him.

Final Gear Ratio- IMO I would not change this out.

Here's what I would do in your shoes... Stick w/ the Vortec super charger (carb pending), get a Stillen Valve body upgrade, everything that Crawford makes, a fujitsubo exhaust, Gordgee grounding wires if you must, and then work on the suspension and wheels. You'll need big rubber in the rear...

Oh yeah, don't forget the gages.
