Dart Pro Block 10.600 Deck Height, freshly honed to 4.601.
We previously had this block listed as a casting flaw but it's definitely cracked along the deck and lifter valley. Please check the photos, maybe you can repair it or run it in a dry application. This was a perfect running motor when it was shipped back to us for a cubic inch upgrade. What happened was it was shipped in the winter from California to Miami and apparently froze in transit and cracked.
The Dart Pro Blocks come with .904 lifter bores, 2.125 cam tunnel raised .600. Spread pan rails for cranks in the 5 inch ballpark. If you know how to fix it, this is a great deal. The block sells for $3700 all day long.
