HP potential for a 9.2:1 360???

Remember with the aluminum the affect or "feel" the engine sees due to the thermal characteristics is the same as having iron heads and 8:1 at that point. So cam accordingly (small). That's why I think the 400hp level is pushing it. If you can get it up to 9.5 or 10:1 static, you can run a cam that has a good chance of making those numbers without it feeling doggy and having plug fowling and carbon issues.
