Here at MC&T, we’ve made no quarrels about our feelings towards Ford’s 7.3L Godzilla V8 engine. Ever since we got a chance to experience the engine inside the Ford F-350 Super Duty Tremor out at Silver Lake Sand Dunes, we’ve known that this modern-day big block is something special. And as impressive as the engine is in its stock form, the aftermarket has proven that the Godzilla V8 has a lot more to give than 430 horsepower and 475 lb-ft of torque. We’ve seen several tuning companies crank the motor up past the four-digit mark, with a little help from some forced induction. The team at Harrop in Australia are the latest madmen to highlight the capabilities of Ford’s Godzilla V8 crate engine, thanks to a Harrop TVS2650 blower.
Ford Godzilla V8: Modern Big Block Powerhouse
Unlike some of the other high-horsepower 7.3L Godzilla V8 builds we’ve seen thus far, Harrop has opted to leave most of the stock engine components in place. The camshaft and heads are as they came from the factory, with the only real changes coming by way of the throttle bottle and fuel system. The team started their testing by leaving the motor naturally aspirated, but with the addition of the Shelby GT350’s throttle body. That was enough to help push the engine up to 550 horsepower, before the Harrop TVS2650 supercharger was installed. Running on pump gas, the blown big block churned out an impressive 803 horsepower.
Of course that simply isn’t enough power for the Aussies, and so it was time for some E85. Running on corn, the stock engine cranked out 944 horsepower and 972 lb-ft of torque on 18 psi of boost. From there, a larger 102-millimeter throttle body was fitted before boost was cranked up to 19 psi. The added airflow allowed for an even 980 horsepower and 980 lb-ft of torque. Again, all of this power is coming from an engine running stock internals without ported heads.
1000 HP V8 Engine
Still not satisfied, the team at Harrop added a bit more boost, for a total of 20 psi. That’s not a small amount of boost pressure, but it’s also not as much as some engines need to make big power figures. With this setup, the stock Godzilla V8 engine laid down 1,015 horsepower and 988 lb-ft of torque on the dyno. That is an incredible feat for both the shop and Ford, proving that the engine is indeed an overbuilt unit. With some ported heads and a different camshaft, there’s no reason why the shop couldn’t add a few hundred more horsepower to that total. Forget the 2JZ, Godzilla has arrived.
This isn’t the first 1,000+ horsepower version of this Ford V8 that we’ve seen, but the fact that this engine is nearly bone-stock is extremely impressive. Some changes are likely going to be made before the engine finds its way into the shop’s Ford Falcon drag car, but we’d wager that’s more to ensure reliability run after run. The craziest thing about the 7.3L Godzilla V8 engine however is its price. Ford Performance will sell you one of these crate engines for just $7,000, which is an absolute bargain. We really can’t wait to see what Ford’s Megazilla crate engine is going to be capable of when it rolls out in the near future. As the old saying goes, there is no replacement for displacement.
