Vette(s): Silver 1974 Convertible - L82 4 speed Low miles (was only 8,900 when I bought it in March 2006) - Now 54K miles. Original owner bought it as an investment for son's college expenses. 2008 Jetstream Blue Convertible

Hmm, a Silver '74 with an L82 and an M21? You know, for some reason, that just sounds like a great car to me!!

Nice find Waz!! Good luck with the upgrades

I wanted a Corvette my whole life, but I never dreamed of all the wonderful people I would meet because of it!

Vette(s): 1973 Red coupe

Sounds like a real nice ride. As for your questions on air cleaner and carb, The cowl induction air cleaner is a good one already. You can gain a little bit of performance if you remove the air door inside the hood. That will let cooler air enter the air filter all the time instead of just when your foot is on the throttle. The switch that opens it is located on the back side of the accelerator pedal and only opens when it is at full throttle.

You can also buy a K&N filter lid so it draws air through the top. I believe the one you would want is the 9". I had one on my 73 for a while but I could not really tell the difference.

The other question, which Carb should you get.

The answer to that depends on the carb you have.

The Quadrajet carb is a good carb if it setup and working properly. If the car is stock then changing the carb will show little improvement. Save some money and have your distributor recurved. That will improve the performance the most unless you want to start with motor and drive train upgrades.

Have fun with your new ride.

Hi Brian - thanks for your info. What you have suggested is a great start for what I need and want at the moment. Down the track I will eventually get the engine re built and toughen it up in the process. But tht will be along way off and for now your suggestions are excatly what I am looking for. I'll defiantly do what you said and see how it goes! Oh - when you say the distributer 'recurved' does that mean getting the point redone for improved timing etc? Cheers

Recurving the distributor means that they/you adjust the amount of travel that the advance will move. The stock distributor will move about 14degrees. So if you start at 12degrees then full advanced will be about 26degrees. Allowing it to travel another 8-10degrees will let it advance to about 34-36degrees. That is where the performance folks say is best for power. The other thing that is done is changing the springs and weights in the distributor which controls the curve/timing of when all this happens. This process is best done on a distributer machine but can be done without that but takes more time.
