| − | Not to be confused with the 351 Cleveland. | + | Not to be confused with the 351 Cleveland. There are no easily interchangeable parts (though with machining, a "Clevor" can be built, but that is for another write up) |
| − | A basic | + | A basic Windsor engine design but with a higher deck height with thicker cylinder walls. |
| + | The bore spacing and bore diameter between the 351 and the 302/5.0 remains the same at 4.38" and 4.00" respectively. | ||
| + | A safe overbore is .030, but some blocks will allow more - before boring beyond .030, the block should be sonic tested for thickness | ||
| + | There are two 351W deck heights, 1969-1970 produced engines are 9.480" with the 1971 through end of production in 1995 at 9.503. | ||
| + | The crank is significantly different with the mains being 3.00" vs the other Windsor engines being 2.25". | ||
| + | The firing order is also different 1-3-7-2-6-5-4-8 (the same as a 5.0 HO) rather then the 1-5-4-2-6-3-7-8 | ||
| − | + | The significant interchangeable parts with other small blocks from the Windsor family are the heads. | |
| + | While the heads are in general, interchangeable, there are differences in the bolting .500 for the 351 vs .438 (7/16") for the rest. | ||
| + | To use a 302 head on a 351, special intake gaskets are needed | ||
| + | Camshafts will interchange but the firing order will require that the distributor cap be wired based on the engine that the camshaft was ground. | ||
| + | Most accessories will bolt up though not all heads are machined for total interchange of these parts | ||
| + | Front timing covers and water pumps will interchange but a word of caution as there are many variations of water pumps and some covers | ||
| + | do not have provisions for mechanical fuel pumps. | ||
| + | |||
| + | A word of caution - Ford used whatever stock of parts was available, no matter what size engine family. A 1972 vehicle might just have a 1970 | ||
| + | coded engine part. Additionally, factory service parts may be whatever is on the shelf, also not necessarily the current year. This means that before you commit money for an upgrade, that you know exactly what you have. | ||
