I would not go 3.73. I would go 3.45 or in that range. And as stated above, a good dyno tune, air intake, and headers and exhaust is the best way to go. I am getting my stock 2000 6 speed dyno tuned later today. I will post the results for you! Look up the zip tie mod for the air intake. It is a free 5-8 horsepower.

3.42's will really wake up the car and is probably the first thing I would do with an auto. You will not see much gain from a catback but LT's with hi-flow cats you will. Gears-CAI-LT's in that order...IMHO.

All depends what you want to do with the car, drag race, auto cross, just cruise. Now find out what gear you have in the car. If its the optional 3.15 gear, I wouldn't waste my time on a 3.42 as its not enough differance. If its the stock 2.73 gear than it would be a nice upgrade. Get a vararam cold air intake for the best results. On the 1/4 mile most people see about 3 tenths quicker and 2-3 MPH faster.
Good Luck.

They are advertising a 60HP gain from this thing. You won't even get that from a full dyno-tune on a stock car. I agree with the advice above; gears, intake, LTs and then get a tune. Mail order from ECS will work for those mods and you'll love it.

It would help if we knew where you lived to point you in the right direction.
Also what you use the car for. Drag Racing, Road racing or just a extra thrill on the street.
Like others have said, gears, vararam, long tube headers & a tune would be a big improvement.
Could just skip all that & get a supercharger or get it all.
Best to talk to a top notch Corvette shop about your needs, I recommend ECS

with the above stated setup:
CAI: used vararam: 250
Used LT's: 700-900
Brand X wet kit with accessories: 500
Tune: 400-600
Worst case scenario, you spend 2500 bucks and potentially have a mid 11 sec car...with Drag radials....

In the long run supercharger is the best bang for buck.
Only regret is it is less fun with doing one big mod vs a few small ones throughout the year to keep me busy.
Went with A&A last year and glad that I did.
