FAQ
Are these pistons standard size or oversize?PDM-3354FCC is standard size. If your block will be bored, see our .020"/.040" options linked above.
What coatings are used on these pistons?They include a thermal-barrier crown treatment and a ceramic/low-friction skirt coating to handle heat and reduce scuffing in high-load use.
Do I need the .100" valve relief (fly-cut) option?If you’re running a high-lift cam or tighter piston-to-valve clearance, the .100" relief helps ensure clearance at operating temperature and RPM.
What supporting mods do you recommend?Head studs, the correct 24V head set, adequate fuel supply/injectors for your power goals, and (for competition) a P7100 conversion if you’re replacing the VP44.
