🦖 Unleashing the Ford 7.3L Godzilla on the Dyno!

Get ready for some serious power from the team at Proformance Unlimited. The 7.3L Godzilla is proving exactly why it's one of the hottest new platforms in the engine industry, stepping up to take the crown in the modern big-block world.

The Setup
In this run, we strapped our 675 Edition Godzilla engine to the dyno to see what it could really do.

Our shop has been working extensively with parts manufacturers to create a massive lineup for this platform, including:

445 cubic inch and 427 cubic inch versions

Custom stroker and de-stroker packages

Setups designed to rival the popular Coyote platform

The Results:

This beast didn't just meet its 675HP rating—it absolutely crushed it. Here are the final numbers from the pull:

Horsepower: 689.6 HP

Torque: 669.7 lb-ft

That is pure, raw, naturally aspirated power ready to tear up the streets or the strip. The Godzilla platform is here to stay! 🏁🔥

Classic Olds Muscle Meets Modern Tech!

There is nothing quite like the sight of a freshly built 455 Oldsmobile powerhouse ready to drop into a chassis. Proformance Unlimited specializes in Oldsmobile builds.

We’ve taken that iconic Olds heritage and brought it into the 21st century with some serious aftermarket upgrades. Here is a breakdown of what makes this engine build so special:

The Foundation: A classic Oldsmobile V8 block, painted in that signature, nostalgic Olds gold.

Modern Fuel Delivery: Topped off with a sleek, black Holley Sniper EFI system. This brings modern electronic fuel injection to a classic platform for turn-key reliability and crisp throttle response.

Front-End Bling: A complete CVF Racing billet aluminum serpentine drive system. Those polished pulleys and brackets don't just look incredible—they offer incredible belt grip and accessory reliability.

Timeless Shine: Mirror-finish Edelbrock chrome valve covers to tie the whole aesthetic together.

Enhanced Airflow: An upgraded high-rise cast aluminum intake manifold sits perfectly under the EFI unit to keep those eight cylinders breathing freely.

This engine is the perfect blend of old-school torque and modern drivability. A true work of automotive art! 🏁🔥

If you are in the market to repower your Oldsmobile project, give us a call at 321-430-2465.

Pure Pontiac Torque: 461 Stroker for a '68 Firebird!

There is nothing quite like the stump-pulling torque of a Pontiac stroker. We are wrapping up this beautiful 461ci powerplant for a lucky 1968 Firebird, and it is the perfect blend of iconic styling and modern performance hardware.

As you can see in the photos, this build is dressed to impress before it even hits the frame rails.

Build Highlights:

The Heart: A Pontiac 400-based block stroked to 461 cubic inches, finished in that classic Pontiac blue.

Cylinder Heads: Equipped with Edelbrock Performer D-Port aluminum heads for massive airflow and weight savings.

Induction: Topped with a high-performance Holley carburetor setup for reliable street manners and wide-open throttle fun.

Accessory Drive: A full billet aluminum serpentine system that cleans up the front of the engine while adding serious "wow" factor.

Details: Chrome valve covers and a CVF Racing pulley setup provide the finishing touches on a show-quality engine bay.

This Firebird is going to be an absolute handful (in the best way possible) once this 461 is dropped in. Whether it’s cruising the strip or light-to-light action, that legendary Pontiac torque is going to make every gear change a blast.
