on the topic of o2 sensors... Your car is obd1 so you just have to lengthen your o2 sensor wires so they will reach the bung, but you don't have rear o2's so don't worry about sims.

The mods you chose are a great starting point. I'd probably wait on the tune until you do a cam (unless you don't plan on doing one). Definitely look into a stall converter it ytou have an auto. Also, don't forget tires. A nice set of Nitto drag radials will be worth as much as the go fast in races.

Good Luck!

LOL...yea i know what you mean. i still have 273s in my car. and its buggin the hell outta me how long these stupid gears are.on the dyno my car seems like it has the longest 3rd gear in the world. just revs forever. ive been in a 373 car and it feels like it pulls so much harder. they will defenatly get you through the powerband quicker, and be a great upgrade from the 273s
