MRE offers a wide variety of aftermarket blocks. Below are just some of the blocks we sell and use with our own buildups. They are available for different makes for any power level you are looking for. With today's technology, using the factory style blocks are sometimes not very beneficial with cost as well their ability to handle power. Most factory blocks will not handle big amounts of power reliably, and are sometimes not very beneficial to the customer to invest the money in them. Below is a list of what is available, and is what we use for our engines.

 

Dart offers different blocks for many applications. We use these the most in anything from mild street engines for those who want the option to upgrade later on, to all out big horsepower engines.
