    3.8 Block Differences between years?

    I have an engine out of a 1990 SC that I am refreshing to put in a 99-04 mustang. I am using Split Port Heads with a windstar intake, and a small turbo. I plan on using a roller from craigslist when I find one in good enough shape to use (not much for sale where i live right now). Does anyone know of any differences in 3.8 blocks between my 90 SC block and the one that would be in a 99-04 mustang? I'm talking about sensors, oil pan, accessory bracket mounts that may be different.

    The only difference I'm aware of is the V6 Mustang had intake runner controls, which you've got covered with a Windstar intake, but there could be some sensor locations or whatnot on the Windstar intake/heads that vary from the Mustang setup. Same goes with the transverse vs. longitudinal arrangement in the engine bay. But I believe the block itself is virtually unchanged from the early 90s up to 2002 or 03 (whenever the Windstar died).
