The 03 COBRA mod motor will fit in a mn12.With out cutting the shock towers.
The v10 mod will also fit.Its not to long,it will go right in.Banks has a blower kit
for it.
I would think that you would need a 03 cobra from the junk yard to keep cost in line.
And own a well equipped shop for fabing brackets ect.
DOWNS FORD
www.downsford.com has a ad out for a 03 cobra complete for $11,900.00.
I would think the best way would go to your local junk yard.And talk to the owner and
tell him your plans.And ask him to put a bid in for a totaled 03 cobra for you.
Haveing hands on a 03 will help you in the swap ,plus every part you need will
be there.or to see the type of part you need to fab.
You can end up with 500 H.P. That would be relieable.And I do not beleive it
would cost much more than a build up of a SC ,that would not be relieable.
I just last week got a price from a SC vendor to build up a SC.He wanted $15,000.00.
with no warrenty.
It would be nice to see you do it.But posting on the SCCoA about it.I think you
will run into 90%+ naysayers.The SC comunity do's not like looking outside
the box,he!! they don't even like looking at the edge of the box.
Good luck on your serch,to due this project.Randy
