Chevy LS2 Dish -27.8cc All std 15 deg/ L92 4.005 bore, 4.000 stroke, 6.125 rod 9.0 to 1 Comp with 63cc head (CP Bullets BLS1004-005)

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.

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.

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.

The BLS1004-005 pistons are designed to achieve a compression ratio of 9.0 to 1 when used with a 63cc head. Ensure that your engine build accounts for the specific head and bore combination to achieve this ratio.

When installing the BLS1004-005 pistons, it's essential to check bore clearance and set appropriate ring gaps as per your engine's specifications. Additionally, ensure that the piston pin bores are properly sized and honed if necessary.

Yes, the BLS1004-005 pistons can be used with aftermarket cylinder heads, provided that the head's combustion chamber volume and design are compatible with the specified compression ratio. Always verify clearances and fitment based on your specific engine setup.

The BLS1004-005 pistons weigh 406 grams each. Lighter pistons can improve engine response and reduce reciprocating mass, but ensure that your engine's balance and rotating assembly are properly configured to maintain reliability.

The BLS1004-005 pistons are designed for a ring thickness of 1.5 x 1.5 x 3.0mm. Ensure you select a quality ring set that matches these dimensions and is suitable for your specific application and intended use.
