**Boostin Performance Stage 3 4B11 Darton Sleeved Short Block** (Evo X/RalliArt)

**Customer must supply engine core with good block and crank, if not a core charge of $3034.53 applies. This core charge covers a brand new OEM block. If a new crank is needed, an additional $915 will be applied.

The foundation of our Boostin Performance Short Block is a freshly cleaned, bored, and honed engine block. Before the block is ready for assembly, ARP Main Studs are installed and the mains are then line honed. The crankshaft is Magnafluxed, balanced, and polished to a mirror finish. What sets our motors apart from the competition, is our precise machining, attention to detail, and some special tricks we have learned along the way!

This Sleeved BP Stage 3 option is the strongest most potent 4B11 short block package we offer! The stock 4B11 block is a open deck design which is not ideal for high horsepower applications. The Darton ductile Iron Sleeve takes care of this issue by completely replacing the sleeve and also fixing the open deck design flaw. I-Beam rods are employed to make use of the short block, which is capable of 900 horsepower, reliabily.
**Darton Wet Sleeving is available upon request. Please contact the shop for pricing/availability as additional charges will apply. This service will also affect the final turn around time frame (typically an additional 45 days).

Compression ratio for this package is 9:1, but other compression ratio's are available upon request. Please include your requested compression ratio in the "NOTES" field of your order.

**This packages does not include ANY shipping fees. Please contact us regarding shipping charges, as pricing will vary depending on location and if lift gate assistance is needed, etc
