In this thrilling episode of Hagerty's Redline Rebuilds, David and John take on the challenge of dyno-tuning a beastly 351 Cleveland engine at Apex Competition Engines. With the winter chill in Michigan keeping them off the roads, the dyno becomes their battleground for perfecting performance. After addressing pesky header leaks and fine-tuning the carburetor, they dive into the heart of the engine to unleash its true potential.

The dynamic duo's attention to detail shines as they tackle issues like hesitation and lean conditions by adjusting the accelerator pump and squirters. With precision and expertise, they optimize fuel delivery, ensuring the engine roars to life with no compromises. By increasing nozzle size and tweaking the pump cam profile, they fine-tune the fuel flow, setting the stage for a power-packed performance on the dyno.

As the revs climb and the engine sings its symphony, David and John work their magic, dialing in timing and fuel levels to extract every ounce of power. Gradually pushing the limits, they witness the engine's response to their expert adjustments, culminating in a staggering 438 horsepower and 427 ft-lbs of torque. The engine's newfound vigor and smooth operation on the dyno promise an exhilarating driving experience once it's transplanted into the waiting car.
