307

I have a 90 buick estate and it has the olds 307 V8. I need to know how to get more power outta this thing. It has a little over 200,000miles so i dont want to go too extreme. Any thoughts?

I have an '86 Regal with the same motor and considered changing the gear ratio in the differential to boost performace. I figured since the car has an overdrive and most of my driving is around town, mileage wouldn't suffer too badly. Good luck
