A mix of computer problems and having the engine tore apart. The latter being the real reason it isn't running. When it was running, the computer would freak out at high RPMs and/or higher boost levels. So, I decided it was time for some major work. At the moment, the heads are just about to come off and reveal whether or not I have the notched or un-notched pistons. Hell, no one even knows for sure what heads the '87 Marks came with. When the '87 Stangs came out they got the new 225hp 5.0 with the E7 heads, notched pistons, and new intake. The VII didn't get it until '88. But, there have been a few '87 Marks found using a combination of either E5 or E6 heads with notched pistons. Gotta love Ford for getting rid of old parts by just randomly putting them on cars. The pistons will dictate my next move. I should really just rebuild the engine anyway, but I'll see later on.
