Chevy 5.3L Stock LS 5.3 Bore 3.809 CH 1.110 Stroke 4.000 Rod 6.125 CR 9.7 Dish Head 62cc (CP Bullets BLS1014-029)

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.

For the BLS1014-029 pistons, a typical bore clearance of 0.0030" to 0.0035" is recommended. However, final clearance should be determined based on the specific engine build and operating conditions.

The BLS1014-029 pistons provide a compression ratio of 9.7:1 when used with 62cc cylinder heads. Ensure that the overall engine assembly and combustion chamber design are taken into account for accurate compression calculations.

Yes, the BLS1014-029 pistons may require specific machining for proper fitment, including honing of the cylinder bores to achieve the correct clearance. Always consult with your engine builder for precise machining requirements.

The BLS1014-029 pistons come with a ring pack featuring 1.5mm x 1.5mm x 3.0mm thickness. Ensure that the ring gaps are set according to your engine's specifications and intended use.

The BLS1014-029 pistons weigh 385 grams each. Lighter pistons can improve engine responsiveness and reduce stress on the connecting rods, but ensure that the overall rotating assembly is balanced for optimal performance.
