Cut down your motor mounts. In the Novemeber '07 issue of MM&FF they tackle that issue. Also I think that they mentioned a compny that made a custom K member for this application. Goodluck, it's gonna be BMF when finished.
There's a guy I know on the local forum I frequent that is doing the same swap into a notch. From what he's saying it's alot of work, It should be an 8 second car when he's finished though. Good luck with the project though.
I remember reading about a full Terminator swap into an '84 Collector Edition (one of the cars with the Shelby stripes/GT-350 badging). IIRC, the only exterior mods were the '03 Cobra wheels, so it must be possible to fit the motor under the stock hood.
MM&FF put one in a notchback, it has been done numerous times already. I'm anxious to see the pics of this buildup. It's been a dream of mine to build a '93 Cobra clone, and swap in a KB'd or Whipple'd termie w/ 6 spd, and IRS.
I researched this same thing for about a month. Be ready for ALOT of work and extra $$$ to put into it. You're talking ATLEAST a 10 year difference in technology so almost nothing will be able to swap over on that end. I am not trying to insult you're inteligence by any means, but make sure you go through EVERYTHING before going ahead with this....PITA. (And as a side note...if you need a Termi engine I have one putting out over 450 HP for sale)
