Ford Short Blocks 331 347 408 4.6L

  HMS DEMON Ford Short Blocks are high performance oriented, meaning we do not build
production stock rebuilds or crate motors. We specialize in the foundation of your Hi
Performance Ford engine. If you're running a forced induction or nitrous combination,
you better have a bottom end to handle the power. Our Short Blocks Deliver Unbeatable
 quality, dependability and Performance.

 Our short blocks are custom hand built for each and every specific application.
 We do not have "production line" short blocks sitting on a shelf, waiting to be sold. Please
 expect 1-4 weeks for build time. All Ford Short Block machining and balancing processes
are done in house using quality equipment such as Sunnen, Rottler and Pro Bal. 

We offer two series of DEMON Short Blocks......Street and Race.

PLEASE read our short block details Carefully when comparing to other companies! You will find we
 use superior products, such as pistons and rods for example. HMS gives Real World details and
numbers. Do you really think a late model 302 based 331 with KB hyper. pistons and 5140 I-beam
 rods will handle 600HP....We know it won't! But others claim this!?? If you have any questions
regarding which series fits your application or any other short block question, Please feel free to ask!
