AJ, I know where you are coming from, and agree with your logic, but disagree with the method. The best bang for the buck in gaining performance form a slant is increase the compression ratio. The stock ratio was advertised at any where from 8.2 to 8.5 to 1. I can't tell you how many slant engines I have taken apart, and not a single one actually measured higher then 8.0 to 1. Most were in the 7.8- 7.9 to 1 area. You can mill the head to get around 10-1, but that is not feasible for a DD street engine. Mill to get between 8.5 and 9.0, and you gain torque throughout the RPM range, which also equates to more horse power. You will also gain MPG. no other changes are required. There is no downside to raising the CR within reason. And it can be done for less money then a converter (which CAN hurt MPG), or a gear change. Then any other mods, if wanted, will be more effective, also
