Why Buy a MMR shortblock?
Because MMR has gone faster than anyone else in the business and knows what it takes to make a high HP engine reliable and street worthy, dont risk it with the "other guys"
Because the Worlds best high performance Mustang shops and Auto Manufacturers rely on MMR shortblocks & engine components for their customers.
Because MMR provides the best and only warranty of its kind on street and racing shortblocks (see our warranty in our policies section).
Because MMR offers the fastest turn around for your custom shortblock with an average of 4-6 weeks to completion (ask anyone else if they can, if they say yes its not custom), have a rush, we can have it too you in 1-2 weeks for an extra charge.
