Frequently Asked Questions

What compression ratio do these Performance Pistons provide for my engine build?

These engines & components deliver static compression ranging from 9.5 to 12.5 to 1 depending on combustion chamber volume, head gasket thickness, and deck clearance. These pistons feature dome volumes from 6cc to 24cc or dish volumes from 5cc to 20cc for fine-tuning compression to your specific fuel requirements. For pump gas 93 octane applications, target the 9.8 to 10.5 to 1 range with these pistons and 64 to 72cc chamber aluminum heads. For race gas or E85, they can support up to 13.0 to 1 with proper quench clearance set at 0.035 to 0.045 inch.

How do these Performance Pistons handle nitrous oxide and forced induction power levels?

These engines & components are forged from 2618 aluminum alloy and can withstand nitrous hits up to 250 horsepower and forced induction pressures up to 15 PSI of boost. The ring package includes 1/16 and 3/16 inch ring grooves with a torsion-resistant 1.50 millimeter top ring for high cylinder pressure. With these pistons, skirt-to-wall clearance should be set at 0.0045 to 0.0055 inch for nitrous and boosted applications to accommodate thermal expansion. For sustained forced induction above 8 PSI, upgrade to tool steel ring sets and add piston oil squirters to control crown temperatures below 450 degrees.

What bore sizes are available for these Performance Pistons in small block applications?

These engines & components are available in bore sizes from 3.995 inches to 4.155 inches in 0.005-inch increments for small block Chevrolet and LS platforms. Standard bore offerings include 4.000 inch, 4.030 inch, 4.060 inch, and 4.125 inch for 350, 355, 383, and 400 cubic inch builds respectively. For big block applications, bore sizes extend up to 4.600 inches for 454 and 502 cubic inch platforms. Each piston is CNC-tuned for weight matching within 0.5 grams per set of eight for smooth high-RPM operation up to 7,500 RPM.

Can these Performance Pistons be used with stock connecting rods and crankshafts?

Yes, these engines & components are compatible with stock 5.7 inch and 6.0 inch connecting rods as well as factory 3.48 and 3.75 inch stroke crankshafts in small block applications. Piston pin height options include 1.560 inch for 5.7 rod 3.48 stroke and 1.425 inch for 6.0 rod 3.75 stroke combinations. Wrist pin diameter is 0.927 inch for standard floating pins with spiral locks retaining the pin. Verify connecting rod big end clearance to the camshaft lobes when using longer stroke combinations exceeding 3.75 inches in factory block platforms.

What clearance specs are recommended for these Performance Pistons in street engines?

For street-driven engines, set skirt-to-wall clearance on these engines & components at 0.0030 to 0.0038 inch using 4032 alloy or 0.0045 to 0.0050 inch if using 2618 alloy. Ring end gaps should be file-fit to 0.018 inch for the top ring and 0.020 inch for the second ring per inch of bore diameter for naturally aspirated builds. Piston-to-head clearance with these pistons should measure 0.035 to 0.045 inch with quench pads if equipped. Follow a 30-minute break-in procedure with conventional 10W-30 oil and varying RPM between 2,000 and 4,000 before sustained wide open throttle.

Does this Performance Pistons require piston-to-valve clearance checking with a performance cam?

Absolutely, piston-to-valve clearance must be verified using modeling clay when using aftermarket camshafts with lift exceeding 0.520 inches or duration above 280 degrees advertised. These engines & components require minimum 0.080 inch intake and 0.100 inch exhaust clearance at 10 degrees before and after top dead center. For pistons equipped with valve reliefs measuring 6 to 8cc, fly-cutting may be needed for camshafts with lift above 0.600 inches and lobe separation under 108 degrees. Always rotate the engine through two full cycles with clay on the piston to measure actual clearance.
