Block Applications: The Man O’War blocks are designed to be a replacement for the small block Ford one piece seal applications, with dipstick located
in timing cover. On rear pan seal it will be necessary to snip off nubs on ends of gasket so that it will fit flush against block.
Block Material: High density Cast iron / 357 T6 Aluminum
Deck Height: IRON 8.200, 9.200 or 9.500 / ALUMINUM 8.200, 9.500 (depending on part number)
Deck Thickness: Approximately .600
Cam Bearings: Standard Small Block Ford Cam bearings
Main Bearings: Utilizes 2.248 or 2.749 Ford style main bearings. (Depending on main size of block) All blocks regardless of main journal size utilize a one
piece rear main seal such as a Mr. Gasket #30 (for 2.248 size) or Mr. Gasket #31 (for 2.749 size) or equivalent.
Main Caps: All five main caps are four bolt with the center three being of the splayed design. The inner row of bolts are ½ inch thread, the outer row of bolts are 7/16 thread, and the outer 4 corner bolts are 3/8 thread.

Torque specs on main bolts are: 100 ft. lbs. inner and 70 ft. lbs. outer and 45 ft. lbs. on the
outer 4 corner bolts with oil.
Lifter Bores: Indexed (Lifter bore size is standard Ford diameter .8750)

Note: When using OE style roller
lifter guides (tie bars) with the spring-steel retainer on a Man O’War block, some material may need to be
removed from the GUIDE where indicated. This should be checked at each lifter boss location. Remove only
enough material in the indicated area for clearance.

Maximum Bore: All IRON blocks can be bored safely to a maximum of 4.200 / ALUMINUM, 4.155
Cylinder Bores: Cylinder bores are a siamese design. Because of increased wall thickness, no steam
holes are needed for street use.
Cylinder Wall Thickness: @ IRON 4.200 bore cylinder wall thickness will be .200
Head gaskets: Use Fel-Pro # 1031L and 1031R or equivalent to ensure water jacket coverage.
Water Jackets: Expanded for better cooling.
Gear Drives & Belt Drives: Due to the expanded water jackets, it is not recommended to run gear drives because of clearance issues with the backside
of the idler gears and the cylinder block in the timing cover area. Jesel belt drives will work with minor grinding of the block and/ or belt drive cover.

Lubrication: There are 2 oil scavenge holes. One hole each is located on both front and back of block but will need special hardware. (Dash 8 AN).
Oil System Features: As is, block is set up for OE style internal oil pump. Block has provisions to be converted to a dry sump oiling system. (On “C”
blocks you must use 351style oil pan, pump, pick up, and distributor but have the oil pump drive rod cut to length.)
Oil Restrictors: Man O’War blocks use oil restrictors special to the block, part # 832665-2. If feeding engine from the front there is only one restrictor
needed on front of block. If engine is rear fed you will need 2 restrictors on back of the block.
Filtration: Integral mount for spin on filter
Oil Pan Rails: Solid (stock width) clearanced for 4.250 stroke with steel rods. Splayed cap blocks may have oil pan interference with the front and rear
main caps. It may be necessary to hand fit the oil pan. Pans rail is tapped 1/4x20 except four outer corners which is 5/16x18.
Clearance: Man O’War blocks can handle up to a 4.250 inch stroke with a 6.300 inch steel H-beam style connecting rod. (9.500 Deck Windsor)

Fuel Pump: Uses stock style fuel pump
Starter: Starter mounting pad is drilled for standard bolt patterns.
Motor Mounts: Drilled and tapped for side mounts in OEM locations. Block may need to be relieved for clearance in certain applications.
Cylinder Head Bolt Holes: Threads are ½” diameter. Head bolt holes are blind tapped and do not extend into the water jackets. Threads are recessed
½” below the deck for greater clamping loads. Bolts or studs need to be ½ “longer than stock. FOR ALL IRON BLOCKS, World #’s 832585 for bolts and #
832552 for studs.

FOR ALUMINUM BLOCKS #832552 for studs. Use #832554 for CHI heads w / studs. It is the builders RESPONSIBILITY to determine
which bolts/studs used will have the proper engagement to prevent stripping the threads.
