I have a stock 1990 Iroc-Z with a TPI 305 and the 700-R4 transmission. After a few repairs (ring job/engine rebuild, tranny adjustments), the car will basically be perfect, 'cept for one thing. A Firebird Formula 350 kinda showed me where its at the other night, and I was wondering what the least expensive way to gain some power to take on people like that (say, to get to a mid 14 quarter mile)...I will basically be starting with no money, since the last bit of money went into my sound system (two 12'' Rockfords in the back and the stock speakers)...HELP! I NEED IT TO BE FASTER!!

 

Lose the speakers and buy nitrous.

I'm not a big racer but I would think its going to be hard to race a 350 with our 305s even with mods (not saying it can't be done). You could start with a cat back that was my first mod. I'm slowly upgrading my car just a lack of money is holding me back a lot

 

If you want the biggest improvement for the $$$ and since this is the power-adder board how about a nice nitrous oxide kit. If you want to be sneaky you can even hide it and let your buddies with 5.7l cars wonder why you put them away with a "stock" 5.0l
