many threads on it if you want to read about it.
SVC made two lincolns - one silver, one black - both with a Eaton mount straight into a custom manifold - so no intercooling. They were on this board a few years ago trying to sell the proto-type and then drum up business for kits. The proto-type was $6k and only sold to someone close to them. The kits were estimated to be $10k - but never sold.
The McLaren used the setup from a s-type r jag - parts alone were of $7k. Ford never worked with them to allow the tuning of the PCM, and the market was too small for an investment to reverse engineer the PCM (at the time). This was before the hand-held tuners like SCT were available. THe car was sold on e-bay, driveline returned to stock, but left the grill and fancy mirrors in place.
