Difference in 94-98 and 99-up

[RedStang88]

What is the difference in the engine of these years that makes a 40-50hp increase? Is it just one parts, or a whole engine?

Better heads I think. Or is it cams? Its one of those two. I think.

Can you switch them out of a 99 to a 94, or would I be better off buying specific heads for my year?

Yes u can switch but you are better off buying specific heads for your year.

it is referred to as "Split-port Swap"

Also there are suspension and drivetrain modifications. 99-00 has a really crappy suspension, 01+ has a much much nicer one. Not anywhere near as bumpy.
