Bore is not neccassarily a factor that limits the power output of the engine. There are many many power producing elements that are over looked. Like everything from Spark plug location, Rod lenght vs. Stroke ratio and a whole slew of others.

While the 4.6 may be a small displacement engine, you can get some pretty damn good power out of it without supercharging it. Pauls High Performance has got 12.8's out of a 260 RWHP 4.6. But thats due to gear and suspension tweaks.

Thats with out any internal changes. Stock Cams, and stock Intake.

For one thing, people like it because its "Diffrent". Despite its apparent lack of cubes, its an impressive motor from an engineering stand point. Its a strong cast block that holds up well, it has a good oiling system, its durable and realiable. I know mines held up to some serouis hard driving, and without so much as a hick up. And I drive mine hard...I'll tell you.

If you look at the heads, check out the valve size. I think its pretty impressive that the power they have can be produced with the smaller than average valve sizes, and a relatively low compression.

Well gotta run off to work now. I didnt get to end my post, but I'll do so later.
