Drag Racing Engines

At Hagedorn Racing Engines, we offer a comprehensive line of drag racing engines tailored to fit a wide range of performance needs:

• Small blocks from 355 cu.in. to 434 cu.in.
• Big block combos from 427 cu.in. to 800 cu.in.
• Available in carbureted or injected versions, wet or dry sump oiling systems, and blown or non-blown configurations.

Our goal is to deliver an engine that perfectly aligns with your racing requirements. While many customers have an idea of what they want, it’s our job to ensure that the engine you have in mind will deliver the performance you need.

Several factors go into building the right drag race engine for your setup. For instance, a 355 small block won’t perform well in a 4,500-pound stock vehicle. That’s why we gather detailed information to create the optimal engine for your specific application.

We’ll Need Key Information Like:

• Vehicle weight
• Transmission type
• Converter stall speed
• Transmission gear ratios
• Rear axle gear ratio
• Fuel type (carbureted or fuel injected)
• Power enhancers (NOS, turbo, or blower)
• Race distance (1/4 or 1/8 mile)
• Tire limitations
• Suspension type
• Header size
• Use of trans brake
• Target speed
• Budget

Once we have all the details, we can build an engine that consistently delivers round after round, getting you closer to the winner’s circle with each pass.

So whether you’re looking to bracket race a 355 small block or take your 200 mph big block Mountain Motor to grudge races, Hagedorn Racing Engines has the expertise to make it happen!
