You will also need a lot of porting and a bigger manifold and a strengthened and filled block. The stock oil system will also be a problem. You will need high pressure and lots of oil. You will also need a roller cam and rockers and big springs; etc, etc. All of this is needed for high power. The stock block bends at high power and so does the crank. The more power the more problems. RPM KILLS! Pontiacs with stock castings are torque engines and should be designed for it i.e. low rpm.

When a B/SA automatic RAM AIR 4 stocker is run, what kind of RPM does it turn through the lights? Or another way to ask the same question, what rear gear do they run?
