“It’s ironic,” chuckled Marc. “Most people want to put a newer engine in an older chassis, and I wanted to put an older engine in a newer chassis.”

Certainly Marc’s solution isn’t a first in the Mustang world, but it has become a lot less common compared to the days of commonplace 351 and 460 swaps into Fox Mustangs, and it gets our attention. The rarity of such events is a clear indicator of how good we have it today. However, some things from the past have stood the test of time. That’s what we’d say about Ford’s canted-valve small-block, whose original genesis came in the form of the ’69 Boss 302 and ’70 351 Cleveland.

Bud Moore was the first to work with the latter engine in NASCAR in the early ’70s, but Cleveland Fords have proven their worth time and time again over the last forty years. In the mid-to-late ’80s—long before Marc’s ’03 Nextel Cup engine—a hybrid of sorts became the standard build by fitting Cleveland-style heads to 351 Windsor architecture blocks. Some call it a Clevor. That arrangement was what all big Ford teams were using prior to the 2009 switch to the non- production FR9 engine now used in NASCAR. But we digress.

After getting the engine from Roush Yates, Marc tore it down for inspection and replaced the flat-tappet cam with a big solid-roller. He also fabbed up his own triple-step headers to mate with the fabulous Yates C3s, routed spent fumes out the sides, and moved the fuel tank rearward to provide adequate space.

Topped with a 950-cfm carb from Quick Fuel Technology, the 358-incher just crested 800 flywheel horse-power at a raucous 8,500-rpm wail. To say the least, it’s a sound you don’t hear coming from a S197 every day!

In the car, the new engine is proving to be everything Marc was hoping for—big time power that will repeat all day long. That’s the on-track report anyway. As for on the road, those days for this former street car are pretty well over, even though Marc reports the car is still licensed and he’s made a few freeway jaunts to nearby Pacific Raceways.

“With the blown 4.6, it was docile in street traffic and I’d drive it to work from time to time. Now it idles at 2,200 rpm, the triple-disc clutch is a bit of a chore on takeoff, and I’d be in trouble if I got stuck in traffic.”

Yes, we’d call the conversion to full-race status complete. While a true competitive debut has yet to occur, Marc is enthused by the potential of AIX coming to the Pacific Northwest in 2014. It’s time to play ball.

This ’08 GT is covered in a factory white wrapper, but it’s hardly subtle. Prior to installation of the full-race 358, owner Marc Sorger reports that local law enforcement pulled him over on the streets several times—but just out of curiosity and appreciation. Marc was impressed that one officer knew enough to think the car was one of the FR500 series builds, and thus checked for a legitimate VIN. He found it, of course!
