When it was time to build the 351W small-block, Allen looked to a variety of sources and helpers. Jamie went to work on Allen's engine, seeking great gains in power. It wasn't easy to get there-especially considering what these gentlemen had to work with. On the surface, it's a deceiving package that is essentially stock on the inside except for 4.030-inch pistons and a hydraulic roller cam designed for supercharging.
Allen looked to Paxton and Nitrous Express for his inspiration, which may have been more than he bargained for in actual practice. Running nitrous and a supercharger together isn't for the lame of heart. You better know what you're doing, and you better have spark curve and fuel delivery down cold before pinning the butterflies-otherwise, engines fail in nanoseconds. That alone should tell you something about this SportsRoof. It is more about show and less about go-hence the engine's rather stock demeanor down under. Rare is the occasion Allen will lay down rubber and show people the power this engine is capable of producing.

Inside, Allen practiced his craft, looking to TMI Products for his inspiration. Check out the carbon-fiber threads from TMI.
Allen looked to The Carb Shop in California to program his 4150 650-cfm Holley for supercharging and nitrous. Milodon provided an 8-quart oil pan to ensure adequate oil supply to both engine and supercharger. He opted for the PerTronix Plug & Play billet distributor sparked by a Flame Thrower ignition coil and ignition wires.
Because Allen wanted the car more true to its roots, he opted for a Ford Top Loader four-speed and a 9-inch with 3.50 gears and a limited-slip. When he grabs the Hurst Competition Plus shifter, it makes it easier for him to relate to the original musclecar era that baby boomers fantasize about today.
That's DuPont Hot Hues Silver Leaf with 20-percent black added to achieve a crystal effect. Allen takes credit for this portion of his effort because this is what he does best. He builds cars at his AC Customs shop in Shreve. Doing a car like this was a natural for him because he does it so well.
Inside is a TMI Products interior from top to bottom in black vinyl. You've gotta love the carbon-fiber look from TMI, which infuses attitude and richness to just about any Mustang interior given imagination. These colors tie in nicely with what Allen did outside. Grant Products did the woodgrain Mustang steering wheel, which offers a classic look. Those are BBK billet-aluminum pedals below; Auto Meter did the instrumentation. Allen provided the monochrome demeanor throughout.
