Moroso 22170 HV Billet Aluminum Oil Pump
The Moroso 22170 HV is a high-volume billet oil pump designed for Big-Block Chevy engines using large-depth oil pans. The 6061-T6 billet housing features 3x larger mounting boss areas to prevent damage from mounting stresses, and it weighs notably less than some cast alternatives. A thrust bearing assembly improves life by handling drive shaft axial forces on the drive gear. Best for racers and heavy-duty street builds that demand robust durability and reliable oil flow, with the added benefit of easier installation due to reinforced mounts. Choose this if you need an HV setup with improved mounting integrity and reduced weight. Be mindful that installation may require compatible pickup and hardware compatible with your pan and block combination.
Moroso 22164 Standard Volume Billet Aluminum Oil Pump
This Moroso 22164 offers a standard-volume billet aluminum pump with a robust 6061-T6 housing. Its 3x larger mounting boss area reduces the risk of breaking under high stress, and it weighs about 1 pound less than a typical stock pump with pickup. The inlet area is enhanced to help prevent cavitation at higher RPMs and demanding oil pressures. Best for: builders seeking improved durability without going to an HV option. Limitations: may need matching hardware to fit your exact oil pan and block configuration.
Moroso 22185 High Volume Oil Pump and Pickup
The Moroso 22185 is a high-volume oil pump configured for Big-Block Chevy engines, with a package that aligns to larger oil flow requirements. The product notes include dimensions and origin details, signaling a “kit-ready” feel for builds that prioritize oil pressure stability at high RPM. Best for: racers and engines that require sustained oil volume during extended high-load operation. Caution: ensure you have compatible pickup and pan dimensions to fit this larger assembly.
Moroso 22190 Billet High Volume Oil Pump
The Moroso 22190 is a billet HV oil pump designed for Big-Block Chevy setups with a .600″ raised cam height. It comes with hardware and shaft, and is compatible with BBC H.V. kits that offer drive shafts for stock location camshafts. Best for: racers running raised cam timing seeking robust oil supply at elevated cam positions. Better for: applications where cam location adjustment is critical. Limitation: ensure correct drive shaft compatibility for your specific cam and block arrangement.
AC-VP3CK-BBC Vacuum Pump Complete Kit
The AC-VP3CK-BBC is a complete vacuum pump kit for Big-Block Chevy builds. It features billet aluminum construction, a 3-vane vacuum pump, a 5″ pulley, and a mounting bracket. Best for: engines requiring vacuum assistance to improve accessory drive efficiency or to stabilize manifold vacuum for certain EFI or carbureted setups. Consideration: this kit adds complexity and width to the front of the engine bay, so verify clearance and belt alignment with your existing components.
Buying Guide
What matters most when choosing a BBC billet oil pump? Durability, fit, and adequate oil flow at your target RPM are crucial. Consider the following:
- Oil pan depth and mounting boss compatibility: Billet pumps with reinforced mounting bosses are less prone to damage under stress.
- Volume needs: Standard vs high-volume pumps depend on engine build, oil pressure targets, and accessory demands.
- Cam height and drive compatibility: Raised cam versions require correct drive shaft length and alignment.
- Inlet and cavitation: Pumps with larger inlet areas help prevent cavitation at higher RPMs.
- Kit completeness: Some models include hardware and shafts; others may require separate components.
- Additional components: Vacuum pump kits add belt longevity and engine breathing improvements but require extra space.
Key practical questions
- Which pump is best for a race-only BBC engine? The HV billet options (22170 or 22185) for higher oil flow and pressure stability.
- Do I need a vacuum pump kit? If your build benefits from improved manifold vacuum or accessory drive efficiency, the AC-VP3CK-BBC kit is a solid option.
- Will this pump fit my oil pan and block? Check pan depth and mounting boss dimensions; Moroso products emphasize reinforced bosses for greater durability.
- Is standard volume adequate for everyday street use? For many street apps, the standard billet 22164 offers a balance of performance and fit.
- What about cam height adjustment? The 22190 and related kits address raised cam positioning with appropriate drive components.
Quick comparison recap
- Best for mounting durability: 22170 HV
- Best value with cavitation resistance: 22164
- Best for high-demand oil systems: 22185

FAQs
- What is the main advantage of billet oil pumps over cast pumps? Greater strength, improved mounting integrity, and resistance to wear under high RPMs.
- Do billet pumps require special installation tools? Generally standard installation hardware is sufficient, but verify mounting bosses and pickup compatibility.
- Can I use a vacuum pump kit with a billet oil pump? Yes, many kits are compatible and can improve engine breathing and accessory drive efficiency.
- Is high-volume always better for a BBC? Not always; it depends on engine build, oil pan capacity, and target operating RPM. Too much volume can cause excess drag or oil aeration in some setups.
- Are these pumps commonly used in racing or street builds? Yes, they are suitable for both, chosen to match the engine’s oiling demands and the intended use.
