NEW SERIES Dart BBC Engine Block 2pc RMS 4.560 Bore STD Deck 9.8 Fully Machined

Dart Machinery has completely redesigned the Big M series Block. They have incorporated numerous improvements and new features to virtually every area of the block.

We now use the New Generation Dart blocks in all of our bbc engine builds. The New Generation Dart block is light years ahead in overall construction as compared to any of the other blocks on the market. Dimensional specs are spot on, and this has been an issue with other blocks we have used in the past. Many of the top engine builders, ourselves included, have found the new Dart block to be superior to the earlier generation Big M series Dart block in many ways.

Note: This block is fully machined but will still require block prep work before use. This involves dremeling, grinding specific areas and chamfering the lifter bores, and installation of cam bearings, as well as extensive cleaning. All of this can be done with hand tools but doe's require extensive knowledge of the procedure. We offer a block prep package, and this includes the special cam bearings used in Dart blocks and the installation of them.
