Mesa Balancing Racing Engines uses only Dart Merlin or Brodix or GM bowtie new blocks to build these high HP packages which on pump gas can make 600 + depending on the cylinder heads and components used and well over 1000 with blower turbo or NO2. These new blocks are put through the same machining process as all our engines (we do not use new blocks without machining them like most of our competitors ) all blocks are inspected for cracks and flaws then fully blueprinted and assembled to fit your needs. Please let us know what the application is, so we can accommodate for the needed clearances your application requires.
All engines use 4340 forged crankshafts or billet upgrade forged H beam rods or billet upgrade.
For the Crankshaft forged 4340 - Billet option, please call for pricing.
