What should i do to my stock 89 C4 to make it a little bit quicker
 

looking to find out what i can do to my corvette to make it quicker headers,throttle body anything really and what brands do you guys suggest

Welcome to the forum. Drop a crate motor in it. Seriously though, anything you do to free up the intake will not be terribly effective unless you free up the exhaust with headers and free flow cats. Then you'll need someone to reprogram the computer to take advantage of the changes.

You want a quicker Corvette? Add a C6 next to your C4 in the garage.
