Mark 8?

all of the mark 8's 96+ have the teksid block. unless it's ovality or cracks prevents .020 overbore the block alone is worth 800.00 machined.


SVTech, dude you should put that motor in a stang with a 96+ cobra intake and cams. it won't torque, but it loves to rev.

a wise man would overbore it .020" and add a 3.75" stroke crank. add some cubes and the heads match better. blown it is hard to top.

a few hundred dollars of machine work, and wellah.

heads: 3 angle, sand the ports smooth. back cut the valves.


i have one (mark8)in the back yard i haven't used yet. i'm considering getting some 3v heads and using that.

I bought it with the intentions of ripping the motor out of it and sticking it in a stang after my wife got done with driving it. She now has a new fusion so the car just sits.
 
the heads don't torque, but they at least are better than 2v in larger cube apps.

any 4v is better :rlaugh: with the tiny bore size of these motors it's the only way you can get decent airflow.. you can't make a 2v head with big enough valves with the small bore we are stuck with. I sure hope on the next generation ford V8 they go with a 4.00 bore.
 
Heads, cams, crank, and intake manifold are some differences between mark VIII and Cobra 4Vs I can think of off the top of my head. What year mark VIII, i think the 97 98 mark VIII motors are better than the 94-96. Different intake and heads. Sounds like abig job, good luck.
