728 HP Chevy MARINE 572 Stroker Complete Engine Package

NOTE: This package is designed specifically by U.R.E technicians for Marine Use with Marine Gaskets throughout with custom Marine Carburetor and custom Marine Distributor System and designed for Pump Gas, for Marine customers who want to feel a real kick in the pants when they push the throttle with 724 HP, all on Pump Gas!

The block and all parts on the 728 HP Chevy Marine Big Block 572 Stroker Complete Turnkey Engine Package are 100% Brand New and Fully Forged from Top to Bottom with forged rods, forged pistons, forged crankshaft, true AFR heads and a brand new 4 bolt main DARTBig M” Racing Block (URE only uses the Dart Big M on Supercharged packages NOT just a regular Dart racing Block). The package is a 100% Complete Turn Key package and when it arrives to a U.R.E. customer it is dyno tested, fully assembled exactly as it came off the dyno, fully broken in, timed, tuned, and ready to drop in and Rock-N-Roll the same day it arrives. The package is 100% Complete and fully assembled including the Custom Marine Carburetor, Marine Distributor, 10 Quart Marine Extreme Baffled Custom Oil Pan, Water Pump, Chrome Pulleys, Air Cleaner, Valve Covers, Manifold, Harmonic Balancer, Flexplate, Spark Plugs, Wires,Looms, Oil Pump, Oil Pan, with the carburetor fully tuned, and the distributor and timing fully set to make installation in any Marine application as easy as possible for all U.R.E. customers. And as with all URE engines, everything from the block itself to the smallest bolt is 100% brand new - NO EXCEPTIONS. When you receive it, all there is nothing to do but drop it in and turn the key.*

The 728 HP Marine Package has been specifically engineered to be a Standard-Deck Height Dart Big M which means that it is the exact same Deck Height of ANY Chevy Big Block like the 454, 502 so if you have a Big Block currently and are replacing it, the 572 Marine Stroker will work with the existing headers you are using. If the customer prefers a Tall-Deck for some reason just let Customer Service know and that is free customization. Most customers prefer a Standard-Deck Height so they do not have to change the headers or mounts they have in the craft in any way whatsoever.

This engine is in URE’s “Overbuilt Line.” It may seem like overkill, but the reason the engines in the overbuilt line are so overbuilt with 100% brand new parts including true AFR heads, fully forged rods, fully forged pistons, fully forged crankshaft and a brand new block is to ensure that no matter what a customer uses the engine for that no issues ever arise.

This 728 HP U.R.E. Marine engine is:

  • Is Fully Customized specifically for a Marine application with Marine Gaskets throughout the engine, a 10 Quart Marine Extreme Baffled Custom Oil Pan, Custom Quick Fuel Marine Carburetor, and a MSD Marine Distributor.

  • Is specifically engineered to be a Standard Deck Height Dart Big M – So it will drop right into any craft that currently has a Big Block in it without any adjustment (Unlike Tall-Deck engines which require massive customization.)

  • Comes with a personalized CD Video of the Dyno on each customer’s exact engine with Full Dyno Documentation

Important Note about Crate Engines: Most other companies that sell crate engines do NOT dyno test their engines. In fact the term "crate engine" in and of itself officially means that the engine is just off the shelf and has never been dyno tested. Whether they are a Chevy Crate Engine, Ford Crate Engine, Dodge or Mopar Crate Engine, Crate engines in general have a bad reputation and for a good reason - usually crate engines do not end up living up to the estimated HP or the quality that the customer thought they were purchasing. And usually crate engines are not individually Dyno Tested. Because most crate engines are not dyno tested, most crate engines usually have an estimated HP NOT a Guaranteed HP. That is why United Racing Engines prefers to refer to URE engines as "Custom Built and Dyno Tested Engines" instead of generic off the shelf crate engines. URE custom builds every engine to be BULLET PROOF, 100% Fully Forged from Top to Bottom, with Fully Forged Rods, Fully Forged Pistons, Fully Dyno Tested, Fully Broken-In, Fully Timed and Tuned on the Dyno and ready to drop in and go exactly as it arrives to the customer.*

* Please call United Racing Engines Customer Service at 1-888-400-4873 (1-888-400-4URE) for information on any URE package and how it will perform with your specific vehicle and driving needs. United Racing Engines Dyno Tests each and every engine individually on the dynamometer. United Racing Engines guarantees in writing that each engine produced by URE will meet or exceed the noted HP & Torque level and guarantees the HP & Torque each engine makes on the dyno on any engine dyno (not an in car chassis dyno), within the industry standard 5% variation from dyno to dyno. Every engine is fully assembled, dyno tested, broken in, tuned, timed, ready to drop in and guaranteed in writing to perform at the HP & Torque levels indicated. All engines purchased from URE are subject to United Racing Engines’ Terms and Conditions. A copy of the Terms and Conditions is available upon request. United Racing Engines specializes in producing high performance street and race engines ranging from 400 to 5000 HP for pump gas, nitro methane and alcohol.
