Will Lincoln Mark VIII block work on 1998 Cobra?

cobra98sd · December 23rd, 2007, 10:48 PM

I have heard that other 4.6l 32v blocks will drop in to a 1998 Cobra Using Cobra heads and intake. If this is true, what blocks match up?

They're the same blocks with very few differences...Something with some side bolts i believe...read around...but yes...I see mark viii blocks used in cobras and GTs fairly often.

they are the exact same block. all VIIIs from 93-98 had the Teskid block as did the 96-98 cobras.

yeah will work with little to no problems

Is there an issue with the difference from automatic MarkVIII to manual stang?

Pretty sure a Teksid block is a Teksid block no matter what way you cut it. If the seller is smart they know what they have.

Yeah its alum block, but the internals are notoriously brittle, on the up side the heads flow better than the cobra ones with forced induction, so ive heard

ive heard the heads on the mark have weak valve springs

Castings are the same as 96-98 Cobras,there is a little difference in valve-train.93-95 have weak valve springs, intake cams have 4 degrees less duration then Cobra ones,exhaust cams are the same.
