what can i do to the engine to make it faster ??? if any body knows

The engine was made by Olds from 1980 to 1990. There is a lot of info on the 307 engine. You can push the timing 2 degrees. Be sure the EGR passages under the carb are open and the EGR is working. Get two replacement carburetor secondary metering rods from a 350 engine. They are easy to replace and will help in higher RPM's. Be sure the secondaries are opening all the way. The biggest problem is the rear end gearing makes it slow off the line.
