How do I know a part fits my engine?
Every listing names one engine application in the title. Confirm your engine code, generation and year against the fitment notes on the listing; see the Fitment page for the traps by family.
What is the free shipping threshold?
Free standard shipping on qualifying orders over $70. Heavy and oversized items (assembled heads, short blocks, cranks, engine stands) ship LTL freight and are quoted at checkout or on request.
Do you ship to shops and builders?
Yes — see the Builder & Shop Program for tiered pricing and terms.
What is your return policy?
30 days on uninstalled parts in original packaging. Electronics and EFI carry a 15% restocking fee. No returns on installed parts, special-order stroker assemblies or custom cam grinds. See Returns & Warranty.
Are your part numbers verified?
Cross-references are checked against manufacturer catalogs. If a listing carries a verification note, confirm with us before ordering.
