I've been reading up on the 3.0L conversion and I think it's a really good way to start making serious power with these cars. I've been saving for a 3.0L block, and I've aquired a second car to drive while mine is under the knife. But before I take the plunge, I have a few questions.
1) Will my MSDS headers still fit? Would I have to use the 2.5L heads or does it even matter?
2) I have an automatic. Will it bolt right up to the CD4E tranny? I know the Taurus uses a different automatic transmission. Terry?

Use the search!!! :rolleyes:
okay now that that is done...
1) yes - same heads... Yes; because of water pump! options - See Search for Details
2) not a problem. But can the ATX handle the torque??? Suggest tranny cooler and shift kit.

The 3.0 crank,auto only, needs the flange grinding/m-c to accept a std flywheel.Bolt pattern same for flywheel or flex plate.Bell housing will fit ,V6 3.0 to 2.5 MTX75.

Bell housing will fit ,V6 3.0 to 2.5 MTX75. let me see if i understand: 1) for an ATX, the crank must be ground to mate to the flywheel. interesting, i thought this was required (only) for the MTX. 2) m-c  3) 3.0 bell housing fits MTX75. CD4E also? assuming the AX4N is stronger, does anybody know if it would fit? crazy, i guess... but curious, too. the gearing is below: MTX75 3.42 2.14 1.45 1.03 0.77 CD4E 2.89 1.57 1.00 0.69 AX4N 2.77 1.54 1.00 0.69

I think he is saying to make the crank fit a standard flywheel for an MTX75 equipped car is when you have to grind the crank......
i may be wrong..

don't know about an ATX, but...
mc = machined
the crank will fit the flywheel regardless, it needs to be shortened so it won't bang the input shaft from the tranny.
The bellhousing is part of the transmission.
