![]() What material/type of rings should be used in a supercharged 25 psi SB 347 stroker motor (e.g. Street Outlaw Class)?
The top edge of the top ring is located .300" from the top of my pistons. The ring package I was sold is described below. The machinist who bored/honed my block commented that I should consider running something else so I wanted to double check before going any further. I obviously can't change the thickness of the rings now but am most interested in the choice of ring material for this high HP, high heat application. Top: 1.5mm Ductile Iron-Plasma Moly-Barrel Backcut 2nd: 1.5mm Cast Iron-Phosphate-Taper Backcut Twist Oil: 3mm std tension oil ring package |
