Can anyone point me in the direction of some modified Lincoln Mark VIII pages? I saw one for sale locally on craigslist recently and was intrigued with its 700hp claims.
It looks like they have the 32v 4.6L, thats the cobra engine from the time, right?
is a good all around knowledge of the MN-12/FN-10 platform.
The Mark VIII predates the Cobra, being introduced in 1993, and had the Teksid block, but no forged internals, so not as capable for high end power as the Cobra. They are however 80lbs lighter than the iron block. If you spend the money on forged internals, some serious boost (turbos usually) and don't mind rebuilding it often you can get some serious power, but on B heads yeah, they don't get anywhere close to that any differently than a Cobra motor does, but with the added cost of forged internals.
What I'd like to do is get a Mark VIII block, put trick flow 2V heads with a 44cc combustion chamber to get about 11:1 or so compression, hot cams, etc.
My 1997 Thunderbird is in the last stage of it's 2003 Explorer engine swap. The 02-05 Explorers with 4.6 had a WAP aluminum block, PI heads/cams/intake and are a great drop in for all iron block 4.6 cars, due to weighing the same as the Teksid block. with the ported heads, stage 2 MHS NA/PI cams, kooks headers, 75mm throttle body, C&L enlarged uppper plenum, and good tune I should be good for at least 350 horse at the crank, which when fed through my 4R70W and IRS is just shy of 300RWHP. All NA and 2V.
I like the 4V motor, but don't like how the torque pretty much doesn't exist below 3500rpm, where on a 2V you start building it up around 1700 or so. If I were ever to go 4V, I'd want a Coyote or Voodoo based block with cross plane crank, basically a big Coyote, with TIVCT for better low end grunt.
