What information do I need to match these pistons to my engine?
You need the engine code, bore size, stroke, rod length, pin diameter and target compression ratio. These determine the correct piston compression height and crown design.
How should ring gaps be set for these pistons?
Ring gaps must be set by your engine builder based on fuel type, boost level and the intended rpm range. Forced-induction engines usually require larger gaps.
Are forged pistons suitable for street engines?
Yes. Forged pistons handle detonation and high cylinder pressure better than cast units. Your builder should set the piston-to-bore clearance to suit your application.
What are the key features of the ACL Race Series conrod bearings for the Chev V8 Small Block?
The ACL Race Series conrod bearings are designed for high RPM applications and feature a high strength overlay plate with reduced thickness, hardened steel backs, increased crush, and tight wall tolerances.

What should I consider when installing these conrod bearings in my Chev V8 Small Block?
Ensure that the conrod journals are properly cleaned and checked for any wear or damage. It's crucial to verify that the bearing clearances are within the manufacturer's specifications, as improper clearances can lead to engine failure. Always follow the recommended installation procedures for ACL bearings.

Yes, the ACL Race Series conrod bearings for the Chev V8 Small Block are available in several options, including normal, with dowel, narrowed, and Calico coated versions. Choose the option that best suits your engine build and intended use.
What is the importance of the hardened steel backs on these conrod bearings?
The hardened steel backs provide enhanced durability and resistance to wear, which is essential for high-performance applications. This feature helps maintain the integrity of the bearings under extreme conditions, ensuring reliable operation in your Chev V8 Small Block.
How do I ensure proper oil supply when using these conrod bearings?
To ensure proper oil supply, make sure to use the correct oil viscosity as recommended for your engine setup. The 3/4 grooving on the main bearings aids in optimal oil distribution, but it's also important to maintain proper oil pressure and check for any obstructions in the oil passages during installation.
