At the time, Doug was working as a mechanic at a company that built and installed traffic lights. He had to save for 10 years before getting the money together for the Montego's major engine modification. That's when he "got the green light," so to speak. (Like we didn't see that pun coming!-Ed.) Doug was at a car show and got talking to a guy who had a blower on his Ford truck. As it turned out he had gotten the blower from L&M Blowers in Denver, Colorado. Doug got in touch with L&M and found out it was using 6-71 Blowers off of Detroit diesels. After acquiring one that was "green and ugly," that's when the madness started. By this time the Montego was being daily driven around town with the original 351W small-block.

By now, some of you may be wondering how much of this was done by the shop. Well Doug, who has been working on and fixing up cars since before he knew how to drive, tells us he did all the work himself, including the blower installation. "We had to build everything from the blower snout, intake manifold to the pulleys," Doug told us. "It was a lot of fun and I learned how to run a vertical and horizontal mill. I even made the air cleaner tops out of billet aluminum."

The original engine's internals were built to handle around 290 horsepower. So, along with the blower install, Doug built up the engine and bored it over 0.030-inch. From the forged Keith Black pistons to the Speed Pro rings to the ported and polished cylinder heads with screw-in studs and guideplates for the Manley valves, this motor is built to take the boost. The fresh Windsor small-block puts out 425 horsepower and 560 lb-ft of torque-enough to scoot the Mercury's 3,900 pounds down the quarter-mile in 12.90 seconds. "When I got it out after putting the supercharger on, it was scary; it was like driving on ice," said Doug.

He obviously learned how to harness the power on the 1,320. The Ford 9-inch rearend may help with this. Of course, at the end of the day a two-ton car going 120 mph needs to come to a stop, just like the article about this car needs to do the same. Taking care of the former is a set of Baer brakes. But to take care of the latter, a concluding paragraph is needed and it goes something like this:

Doug Freyta started out as a mechanic at his company 22 years ago, around the same time as he bought a battered Mercury Montego. Today, after growing with the company, he sits in the head office, running the show and this fully revamped version of a rare Mercury that you hardly ever see stock, nonetheless modified to this extreme. Oh, and for the record, we asked Doug if he had a mullet back in the day and he said no. But we don't know; there could be pictures.
