Supersizing applies to engines as well as French fries.
Our friends at Auto Revolution prove the point with these videos showcasing the build and dyno results for an awesome 448-cubic-inch small block Ford. Pass the ketchup—er, motor oil, please.
The engine was built by Peter Guy of Peter Guy Racing engines in Fresno, CA. Originally from New Zealand, Peter has been in the States since the early 1980s, making a name for himself building silly-big powerboat racing engines with the likes of Art Whipple and Pacific Marine. Peter races what he builds, too—he’s won three consecutive American Power Boat Association (APBA) national championship titles as a driver and numerous events as an engine builder.
When Peter was visiting New Zealand last summer, he stopped by an old school mate’s garage to see what he was up to. While at the shop, they talked about building the perfect street car engine for the friend’s 1969 Ford Mustang Mach 1 (A very rare car in New Zealand.) The Mach 1 just went through a full restoration and was ready for a new drivetrain.
After spending quality time at SummitRacing.com, Peter decided on a 448-cubic-inch small block Ford. Based on a Dart SHP block and an Eagle/Ross reciprocating assembly, the 448 features Trick Flow Twisted Wedge® 11R 205 cylinder heads, a COMP Cams Xtreme hydraulic roller cam, and a Holley 750 cfm double pumper on an Edelbrock Performer RPM Air Gap intake manifold. Peter used a bunch of Summit Racing brand parts too including a Street & Strip® distributor, CD ignition box, and coil; SFI harmonic damper; fuel pump; starter, and oil pump kit.
The 448 was dynoed by Steve Moody at Auto Machine Specialties (A.M.S) in Fresno. The engine made 550 horsepower at 5,600 rpm and a whopping 569 ft.-lbs. of torque at just 3,800 rpm. That’s the makings of an awesome street engine.
Peter has since crated the engine and sent it to New Zealand. He plans to fly over, install the engine in the Mach 1, and then go out and terrorize the old neighborhood with his mate, just as they did as kids.
Don’t you love a happy ending?
Sit back and listen to Peter describe how he assembled and dynoed the 448 in the videos below. Then, check SummitRacing.com in the near future for 448 Parts Combos that feature all the stuff used in this build.
