Done a complete rebuild down to the block. Used these piston rings, they were gaped perfectly, and first start up and break in no blue smoke and the rings sealed perfectly. Highly recommend these for just a regular rebuild on a motor. ## Frequently Bought Together - ENGINETECH R40058-STD CAST PISTON RINGS (4.000" BORE) compatible with CHEVROLET SBC 302 327 350 400 / FORD 289 302 351W 351C 351M 400 / CHRYSLER JEEP 327 360 - Permatex 81950 Ultra Slick Engine Assembly Lube, 4 oz. , Red - Partsflow Full Engine Gasket Set for 1963-1982 Ford 260 289 302 Ford 302 Full Gasket Set Fits 1968-1982 Ford 302 V8 2 Piece Rear Seal P/n F302-4 4.3L 4.7L 5L V8 OE#260-1125 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/144098444-enginetech-r40058-std-cast-piston-rings-4-000-bore-compatible](https://www.desertcart.co.uk/products/144098444-enginetech-r40058-std-cast-piston-rings-4-000-bore-compatible) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-14*
