Although this option is more expensive and will require you to pay the associated new block/head charges, it will allow AAM Competition to build you a new motor without having to send any components to us to be re-used. Yes! AAM Competition is able to put together an entire motor using a new OEM block and/or OEM heads at your request.
Our current workload will also play a role in determining a timeline for project completion.Ĭan an engine package be built without using my core components? Upon receiving useable cores, AAM Competition is able to complete most engine packages within 3 – 6 weeks, but this timeframe is not a guarantee and may vary. Turn-around time depends on many things, including the specific stage/level of your desired engine package and availability of components. What’s the expected turn-around time for a VQ37 engine package? See AAM Competition’s Terms and Conditions page for more information. The amount of your refund will be determined based on the condition of the core and is at the sole discretion of AAM Competition, LLC. All cores will be thoroughly checked and tested upon arrival at our facility to determine their condition. In order to be eligible for a refund we must receive your core(s) within 30 days of when your AAM Competition product shipped to you. 11.0:1 is a higher compression ratio than the factory-spec engine, making it a great option for naturally aspirated builds looking to make more power and/or take advantage of higher octane fuels.Ī core charge is an expense that is added if the customer does not wish to send in core units (engine block and/or heads) to be built, or the returned core units are not complete or are not in rebuild-able condition. 9.0:1 is a lower compression ratio than that of the factory-spec engine, making it ideal for forced induction applications, such as supercharger, turbo, and twin turbo setups.
