GM ATK 100% New Crate Engines

ATK is now offering 100% New engines based off a New American Made Bare Block. Lead times on these engines should be much faster as we are not dealing with core issues on these builds. These engines will come in a standard bore size allowing you to keep more cylinder wall for future use.

ATK is charging a core charge on these engines which is built into the pricing. This allows us to offer the engine at a more attractive price for those that have a core to return. If you return a rebuildable 350CI long block engine core, ATK will reimburse you $410.00.

****Short Blocks do not have a core charge therefore no refund will be issued****
