93 - 99 4.6 Teksid aluminum block. By far the lightest and strongest factory block. The 4.6 iron blocks are just as strong,.. just not as light. Will easily hold 1000 - 1200 hp. Many have seen 1500 - 1600 hp with work done to them.

Used in 93 - 98 Mark8, 96 - 99 Cobra, also used in fwd Continental,.. but bell housing design makes converting to rwd difficult. There is one more that got the Teksid block,.. and for the life of me,. I cant remember what it was. Its a Lincoln I'm pretty sure.

Factory 302 blocks are not known for lasting very long in high RPM, high HP configurations.
