guess a lot of the number's just rely on what and where suppliers get their stuff.

99 is when the 4.0 changed heads and manifolds with the small exhaust ports.

its also the year that if you do swap over the inlet manifold to an earlier engine you do get up 15hp increase apparently as it flows more air .
