{"product_id":"ford-351w-mid-dress-crate-engine","title":"Ford 351W Mid-Dress Crate Engine","description":"The ATK Engines HP09M is a Ford 351W mid-dress crate engine designed to deliver enhanced performance with 300 horsepower and 377 lb-ft of torque. It is built upon a seasoned OE roller block, compatible with models from 1987-1995, and boasts a 351 cubic inch displacement.\n\nThis engine features a robust set of internal components including an OE crankshaft with a 1-piece rear main seal and 28oz balance, OE connecting rods, and hypereutectic pistons achieving a 9:1 compression ratio. Moly rings ensure durability, while a hydraulic roller camshaft with specs of 220\/224 at 50, .512in\/.512 ex lift, and a 112 LSA contributes to its performance profile. A double-roller timing chain provides reliable timing, and it is fitted with OE #E7TE cast iron cylinder heads featuring 1.77-inch intake and 1.46-inch exhaust valves, paired with stamped steel 1.6 ratio rocker arms.\n\nCompleting the mid-dress package, the HP09M includes a rear sump truck oil pan, a Melling standard volume oil pump, and an external balance 28oz harmonic balancer. A Pioneer external 28oz, 164-tooth flexplate\/flywheel is included. For induction, it features a Weiand Stealth dual-plane intake manifold and a Pro-billet distributor with an upgraded melonite gear. A later model LH inlet water pump is also part of the assembly.\n\nATK recommends specific components to achieve optimal performance, including a Quick Fuel 670 CFM vacuum secondary electric choke carburetor, a mechanical fuel pump rated at 80-110 GPH, Autolite #24 spark plugs, and 8mm spark plug wires. For operation, use conventional non-synthetic 10W30 oil and a Wix or K\u0026amp;N oil filter. Timing should be set to 34-36 degrees with the vacuum port plugged, spark plugs gapped at .035”, and requires 91+ octane fuel. A stock stall converter is recommended, and the exhaust should utilize 1 5\/8-inch headers. It's important to note that power figures can vary based on the end-user's component choices, and some vehicle modifications may be necessary. ATK reserves the right to substitute parts if required.","brand":"ATK Engines","offers":[{"title":"Default Title","offer_id":52867460432184,"sku":"HP09M","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687938703.jpg?v=1787911078","url":"https:\/\/store.motormia.co\/products\/ford-351w-mid-dress-crate-engine","provider":"MOTORMIA","version":"1.0","type":"link"}
