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 benefits of using ACL Race Series Main Bearings in my Chrysler 5.7L Hemi engine?
ACL Race Series Main Bearings are designed for high-performance applications, providing enhanced durability and reliability under higher RPM conditions. The high strength overlay plate and hardened steel backs ensure these bearings can withstand the stresses of racing or performance driving.
Do I need to modify my engine block to fit these main bearings?
Typically, these bearings are designed to fit the Chrysler 5.7L and 6.1L engines without modification. However, it's essential to check for proper fitment and ensure that the engine block is in good condition. Line boring may be required if the main caps have been altered.
What machining processes should I consider when installing these main bearings?
When installing ACL Race Series Main Bearings, ensure that the main journals are properly polished and within OEM specifications. It's also advisable to check the main cap alignment and perform line boring if necessary to maintain tight tolerances for optimal performance.
What is the recommended oil clearance for these main bearings in a performance application?
Oil clearance for ACL Race Series Main Bearings typically depends on the specific application and intended use. For high-performance builds, a clearance of 0.0015" to 0.0025" is common, but always consult with your engine builder to determine the best clearance for your setup.
How do the features of these main bearings improve oil flow in my engine?
The 3/4 grooving design of the ACL Race Series Main Bearings optimises oil supply to the bearings, ensuring consistent lubrication under high-stress conditions. This feature, combined with increased crush and consistent wall tolerances, helps maintain reliable performance during operation.
