Parents play a significant role in shaping the lives of their children. Teenage angst and rebellion against parental control is a normal stage in the emotional development of most young people, and for Tim Crotty, this rebellion led him down a road of fun and fast cars.

Growing up in the '60s, Tim loved hot rods with big power, and the car that started it all for him was a '66 427ci, 425hp Corvette convertible. The muscle-car movement was in its heyday, and American youth was in love with the hot-rod culture.

As for the rebellious part, well, it all started with a haircut.

"When I was a kid, I had long hair," Tim explains. "My mother hated it. So she made a deal with me. All I had to do was get a haircut, and I could get whatever car I wanted. I got my Corvette, and I was hooked!"

Over the years, Tim's love for fast cars has only gotten stronger. Having owned a variety of iron from Mustangs and Corvettes to Porsches, he always came back to the Mustang. Tim's newest machine is this '07 Mustang GT that's been fortified with a slew of Shelby hardware. It embodies the classic hot-rodder character and rebellious spirit that Tims's '66 Corvette possessed back in the day.

"A friend had just bought a twin-turbo Porsche for about $130,000," Tim said. "While we were talking about it, I started laughing and told him I'd build a little Mustang and whup him for half of what he spent." After that conversation, Tim's search for a Pony began. "I have a few friends in the car business," Tim explained, "I knew I wanted a white convertible with a black top. A good friend told me about Arizona Shelby Cobras in Wickenburg, Arizona, so I gave them a call. Richard Creel helped me find a car, and took care of the financing and the post-title Shelby performance package. Before I took delivery, Shelby did the suspension and engine work, including a Roush supercharger."

Tim instantly fell in love, but in typical hot-rodder fashion, eventually there wasn't enough power to satisfy his needs. Back in his home state of Florida, his heavy right foot led him to Blow-By Racing (BBR) in Boca Raton, where Chris Jones worked his magic on the Three-Valve. "When Tim brought the car to us it made 372 rwhp," Jones tells us. "We changed the supercharger pulley and it responded well." With a smaller pulley, Tim's mod mill laid down 427 rwhp on BBR's Dynojet. Though Tim got the fix for his power addiction, the itch would soon be worse than before.

"When I got the car back from BBR, it was a lot of fun, but it just didn't blow my skirt up," Tim jokingly stated. "I had become pretty friendly with guys at Blow-By, and I asked them what we could do to make my Stang something really special." With the bar set high, the BBR crew set out to design and build a motor that would blow his mind.

The BBR engine started with a Kellogg crankshaft sporting a 3.75-inch stroke and Manley rods to raise and lower the CP pistons that fill the 3.575-inch bores, bringing the total displacement to 301 cubes. The bottom end is held together with ARP fasteners, and a Moroso oil pan holds enough lubricant to feed the stock oil pump.

Next Jones bolted on a set of BBR's Stage 3 ported Three-Valve cylinder heads. Post-CNC machining, BBR's Stage 3 heads flow 292 cfm at 0.600-inch lift, a healthy improvement over the stock 224-cfm flow numbers from the factory. When all is said and done, the combination produces a boost-friendly 8.8:1 compression. BBR's Stage 2 camshafts manipulate the stock-size Manley valves, which allow the air/fuel mixture in and exhaust gasses out. Once combustion is complete, gasses exit via American Racing Headers 1 3/4-inch long-tube headers and X-style mid-pipe. Thanks to a 21/2-inch Magnaflow axle-back system, Tim's convertible has that powerful Mustang tone.
