BBM Cast Iron FE Engine Block (FE427 Side Oiler)



 

BBM Cast Iron FE Engine Block

NHRA   Accepted for STK & SS

The new BBM FE engine block is significantly stronger than the stock block and is ideally suited for both restoration and high performance purposes.  It has a larger bore capacity, allowing for much larger displacement engines without the cylinder wall weakness issues that have plagued the stock OEM blocks.

BBM cast iron FE block features include:

• Exterior appearance to original 1965 FE OEM sideoiler blocks

• Original true sideoiler oiling system

• Enlarged main oil passages

(As is customarily done by most FE experienced engine builders to OEM blocks. No oiling system modifications will be needed with the BBM block)

• Screw-in “freeze” plugs

• .750 inch thick deck for incredible strength and rigidity

• Cast with siamesed cylinder walls for maximum strength and bore capability

• Water jackets are cast solid, right up to the bottom of lower core plugs to maximize cylinder strength and support

• Max bore capability 4.440 inch, bores are 4.245-inches to be finish honed to 4.250 inch

• Accepts a 4.375 inch stroke with no modification necessary

• Stock 10.170 inch deck height

• ARP 12 point Cross-bolted main caps upgraded from stock 3/8 to 7/16, interference fit amid the block skirts without spacers. Locating dowels in the main saddles ”Lock” the forged and heat-treated 8620 steel main caps in place

• Down under are heavier, thicker main webs and pan rails for superior strength

• All cylinder head oil feed passages are tapped with 5/16 – 18 threads for easy placement of an oil restrictor if the use of a restrictor is desired

• Standard ARP main studs supplied and installed

(You may use standard ARP head bolts)

• Bosses cast in place for SOHC “Cammer” head oil drainbacks, ready for drilling if needed

• Machined and drilled for full hydraulic lifter capability

• Strengthening ribs cast into lifter valley area for increased rigidity and strength

• Main oil galley passages are larger than the factory originals for increased oil volume

• Accepts both FE and Cleveland main bearings. Tangs are machined for both, allowing a wider choice of performance bearings
