IAII BLOCK
-
Siamese Cylinders: 4.170 to 4.400" bores with min. of .200 wall thickness @ 4.400 bore. This provides outstanding cylinder wall rigidity. No other block has this
-
All steel registered main caps: With splayed four bolt pattern on the three center mains which adds rigidity
-
Block cast: Allows clearance for 4.750 stroke crank.
-
Main webs: Strengthened to maximum width possible.
-
Cam tunnels: Reinforced.
-
Wider pan rails: Provides better oil pan gasket sealing and gasket retention.
-
Thicker deck surfaces: Provides added strength and aids in cylinder head sealing
-
Solid lifter galley: With drilled oil returns that prevents lifter bore breakage and adds strength
-
Improved oiling: Front main oil feed, which adds longevity and helps prevent front main bearing "starvation".
-
Bottom of the block: Is solid to the bend, above the pan rail, for added strength
-
IA II Blocks have Redesigned Block Cooling Passages: Improves cooling to all cylinders.

Provisions for external cooling: 1/2" NPT holes provided at rear of block. Gives you the option to dry deck the block.

Dual bell housing bolt patterns: For both Pontiac and "corporate" housings.
-
Lifter bores: Are deeper to allow the use of standard type "corporate" lifters.
-
Bottoms of cylinders: Are notched to clear strokes up to 4.75". A 5.0" stroke is possible with some grinding.
-
Head bolt bosses: Are tied to cylinder walls and the exterior block walls are thicker for added strength.
-
Oil filter passages: Are threaded for easy remote filter mounting. Oil pump passages have corner plugs at 90 degree turns to reduce flow restriction. (Plugs are included with kit.)
-
Threaded front external oil passage: for lubricating superchargers or turbo's. The IA II Block uses standard Pontiac 5 bolt Motor mount pattern.
-
Standard deck height: IA II Blocks are available with 3" or 3 1/4' ' mains .
-
Threaded freeze plug holes: For safety and wall rigidity. (Freeze plugs are provided with block.) This lessens the chance of the engine blowing out a freeze plug.
