Get ready to rev up your engines, because we're about to dive into the story of Brad Johnson's Pontiac Firebird Formula 400, a true automotive masterpiece! This iconic ride has quite the journey, and we're here to share every thrilling detail.
Imagine this: over nine years ago, Brad embarked on a mission to bring this 1974 Firebird Formula 400 from Rockhampton to the Gold Coast. Initially, it was powered by a stock 350ci Pontiac engine, a TH400, and a 10-bolt diff. But Brad wasn't satisfied with just cruising the streets; he wanted to create a beast that would leave everyone in awe.
So, he decided to join the power-chasing crowd and made a bold move - swapping the 350 for a period-correct 400ci Pontiac engine. But that was just the beginning of this transformation. Brad's vision was to create a powerhouse, and he did just that!
Under the hood, you'll find a built-for-boost 370ci LY6 cast truck block, a Callies crankshaft, Wiseco BoostLine rods, CP pistons, and MLS head gaskets. The Brian Tooley turbo camshaft and Tremaniac CNC LS3 cylinder heads add an extra kick of power. And let's not forget the one-of-a-kind valve covers from Swiftek Engineering in Queensland - a true work of art!
But here's where it gets controversial... Brad didn't stop at just the engine. He completely revamped the car to match its new, powerful direction. He installed an FTI Stage 4 TH400 with a transbrake from Summit Racing and a matching 9-inch billet converter. The braced 35-spline housing, Strange billet HD Pro center, Truetrac, and 3.5:1 gear ratio ensure this machine handles like a dream. And with 11-inch disc brakes, you know this Firebird can stop on a dime!
The Firebird rides on Outlaw Drag Intensity wheels - 17x4.5 at the front and 15x10 at the back. These bad boys are wrapped in Nankang 165/75R17 and PSR 275/60R15 tires, respectively, providing the perfect blend of style and performance.
And the results? Well, they speak for themselves. Brad took his Firebird to Cleveland Dyno to see Scott Hoffman, and the numbers don't lie. This beauty pumped out an impressive 660hp on pump 98 and an astonishing 801hp on E85 to the hubs!
So, there you have it - a true automotive masterpiece, crafted with passion and precision. Brad Johnson's Pontiac Firebird Formula 400 is a testament to the power of innovation and the pursuit of automotive excellence.
And this is the part most people miss... the journey is just as important as the destination. Brad's story is a reminder that building a dream car is a labor of love, and the rewards are truly satisfying.
