dished vs flat top pistons, different rod and stroke length.

The 4.8 is clearly the superior motor.

4.8 pistons are flat, 5.3 pistons are dished.
4.8 crank has a shorter stroke than the 5.3.
4.8 rods are longer than the 5.3's.

I don't think one is "superior" over the other, they are just different.

Yes, it's a lot like Star Trek the Next Generation. In many ways it's superior, but it will never be as original as the first.

The 4.8's hp maybe rated 10 less, but there's a huge difference in tq.
