RWA1688 2.0 Aluminum Bare Block

This YB Aluminum Cylinder Block is a direct Motorsport replacement for the original Ford Cosworth YB 200 Iron Block. Manufactured from genuine Grainger & Worrell castings, they are cast in special A356 alloy and heat-treated to T6 condition for uncompromising strength.

The block is designed for both Turbocharged and Naturally Aspirated engines; it can be used in wet sump and dry sump applications.

Steel main bearing caps are included and installed using an ARP stud, washer, and nut kit. The thick wall bores accommodate special ductile high strength iron liners in 90.8, 92, 93, 94, 95 or 96mm bore sizes. The deck height can be finish machined to any height between 207.5mm (Original Specification) and 221.5mm (+14mm) if desired.

Unlike the iron block with limited material beneath the threaded head bolt/stud holes, this block features large cast pillars that extend internally from the deck to the crankcase portion of the block. This allows the head stud holes to be machined for either standard head bolts (or an aftermarket head stud set) or for special deep engagement long-studs (designed for big HP engines and high boost applications).

The combination of large internal pillars, thick cylinder walls and deep cast deck provides a very strong and stable block.

The crankcase area of all blocks are suitably machined to accommodate all strokes of cranks up to 88mm and are fitted with a special clearance breather baffle as standard.

Each block is meticulously prepared and arrives with finished honed liners, steel main caps, ARP main cap studs, bungs, core plugs, ring dowels. Blocks can also be optionally supplied and fitted with oil squirt jets.

Weight: 94mm Bore / +10mm Deck Alloy Block – 25kg (This weight includes the liners, bungs, core plugs, studs, ring dowels, and steel main caps).

Includes long head studs and oil squirt jets.
