3SX Carries Custom Forged Aluminum Pistons from Ross Racing Pistons!
These are the very pistons that powered both our T2 and T4 drag cars to their various records – pounding out a mere 996 AWHP on our AWD drag car and 820 FWHP on our FWD drag car. Want a bullet-proof botom end? Start with our Ross pistons! That’s what we do… Our forged shortblocks are built with none other than THESE very pistons.
These options are now offered:
91.1mm bore (stock bore) with increased 8.5:1 compression ratio
91.5mm bore (.5mm or .020″ over) with increased 8.5:1 CR , ~3.02 liter displacement
92mm bore (1mm or .040″ over) with increased 8.5:1 CR , ~3.05 liter displacement
93mm bore (2mm or .080″ over) with increased 8.5:1 CR, ~3.1 liter displacement
These are oversized pistons that require a cylinder bore to be used. They have larger valve reliefs to fit oversized valves and offer better clearance on the valves. Kit includes a complete set of 6 pistons with wrist pins as well as matched piston rings.
