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 Main Bearings for the Holden GEN V LT engine?

What should I consider regarding lubrication when using these main bearings?
Ensure that the oil system is capable of delivering adequate lubrication to the ACL Race Series Main Bearings. The 3/4 grooving design enhances oil supply, but it's crucial to maintain proper oil pressure and quality to prevent premature wear.
Are these main bearings compatible with aftermarket crankshafts?
The ACL Race Series Main Bearings (5M7292H) are designed to fit the OEM specifications of the Holden GEN V LT engine. If using an aftermarket crankshaft, verify that it maintains the same dimensions and tolerances to ensure compatibility.
