The short block is where reliability starts

Every Crawford Essentials short block starts as a brand-new OEM Subaru block — never a used core, never a rebuild. We fit upgraded bearings, assemble it to order, and ship it ready for your heads and accessories. It is the stock block, done better than original — that is what BTO stands for: Better Than Original.

Why it lasts

  • Brand-new OEM block

    No core charge, no core return, no used block with an unknown past. Your build starts from zero miles.

  • Upgraded bearings

    The known weak point, addressed. Upgraded bearings are fitted as standard on every Essentials short block.

  • Built to order

    Assembled for your order at our East Coast facility — never pulled from a shelf of pre-built stock.

  • Backed in writing

    Every engine carries a 1-year / 12,000-mile warranty, with extended coverage available.

The Essentials short blocks

Break-in is part of the build

Oil changes at 500 and 1,500 miles. Vary engine speed between 2,000 and 4,500 RPM. No sustained cruising, no full-throttle pulls, and no more than 80% of target boost until break-in is complete. The first oil analysis is mandatory — it is a condition of the warranty, and it is how we both know the engine is healthy.

Covered for the first year

Every Crawford Essentials short block is covered by a 1-year / 12,000-mile warranty. Extended engine coverage is available if you want more.

Read the Motor Warranty

Four blocks. One standard: new, upgraded, and built to order.
