TECHNICAL SPECS

• Siamesed Cylinders: Standard  4.125” cylinders. Extra-thick walls prevent cracking and produce excellent ring seals.
• Scalloped Water Jackets: Increase coolant flow around cylinder barrels to prevent detonation, extend engine life, and produce consistent cylinder temperatures.
• Steel Four-Bolt Main Bearing Caps: Sportsman Blocks have three 4-bolt center caps with splayed outer bolts for maximum strength, Race Blocks feature all five 4-bolt mains, rear cap uses a standard 1-piece seal.
• Stock Components: Provisions for stock motor mounts, accessory drives, smog pumps, starter brackets, oil pans, and pumps.
• Upgraded Oiling System: Has a complete stock-type system plus a low-tension priority main oiling system with front and rear external oil pump feeds.
• Dual Crossovers: Allow oil flow to be metered with restrictors for roller lifter cams and/or roller rocker arms to reduce oil flow and windage.
• Reinforced Head Bolt Bosses: Blind-tapped to prevent leaks and produce accurate torque readings. Extra-thick decks prevent head gasket leaks.
• Standard Camshaft and Cam Drive: Standard cam and cam drive can be used. Lifter Valley of Sportsman Blocks has provisions for the production of hydraulic roller lifters.
• Precision CNC Machining: Ensures consistent high quality and eliminates expensive ”blueprinting”.
