Core Charge


We require a full payment for the motor build upfront and we will only charge you for the core charge once we inspect your engine and deem it not usable for the engine build. We can offer a 65% minimum down payment on your engine build please email for more information on this option.

You have the option of using a brand new block in the event that your block is unusable as a core. It is often cheaper to replace your entire block with a brand new one then paying the core charge because you avoid all of the machine work costs associated with restoring a used block to factory conditions and shipping cost associated with shipping your block to and from Speed Perf6rmanc3. This option is great because you receive a completely new long block from the factory with all new internals including the head and valvetrain.

All core parts sent to us MUST be free of cracks, scores, chips, pitting, non-factory coatings, heat damage, and other defects. We reserve the right to reject any or all of the core parts.

When you remove your used block from the car you much wash it out as best as possible with a good degreaser and send it back to us in one piece without disassembling it.

Details of what we consider an acceptable core are outlined below. Any missing components will be deducted from the core charge based on our cost for the missing part.

  • Block
