Hey guys, it appears that some way or the other I have blown a head gasket or had some other kind of "pull my motor out and tear it apart" problem. Something went very wrong because it grenaded at 2500 rpm on the interstate. Its a Pro-line/Promotion combo with a t-trim (11 lbs.) boost. Anyhow, when I bought the car, I was 28 and now, I'm 43. I have kind of realized that 400 rwhp is plenty for a fun weekend car and that is what the Cobra will stay. For a while now, I have started to get a kick out of the idea of a mid (425 rwhp) level auto car. With a blown engine, I have been kicking around the idea of a Mach 1 Auto drivetrain swap. So, that being said...if you had the entire engine, transmission, harness, computer, everything...how much of a nightmare is the Mach 1 Auto swap into a 98 DOHC car? What is gonna end up being the sticking points in such a job?
