Ford V8 Engine Differences There are different types of Ford engine’s including the Windsor, Cleveland, FE, and Big Block types. The 289 is the smallest of the popular Windsor engines. It was produced from ’63-’68 and is very similar to the 302 except for the stroke. Most all 289’s and 302’s have mechanical camshafts and press in studs. A 289 has a 4.00×2.870 Bore and Stroke while the 302 has 4.00×3.00.
The 302 Boss and SVO has the same Bore and Stroke. The 302 manufactured from ’85 and up has roller type camshafts. The 351 Windsor is the biggest smallblock Ford engines. It has a Bore and Stroke of 4.00x.3.50. It was made at the Windsor, Ontario plant.
The 351 has a beefier block than the 302/289 but has the same bore spacing and bore diameter, so the heads retrofit. The deck height is taller and the Mail journals larger. Camshafts interchange but the 351W has a different firing order except for the ’82 and later 302HO. The Windsor has been in production since ’69. The 351 Cleveland is in a class by itself and entered the scene in 1970 until 1974.
It has canted valves and multi-groove keepers, hydraulic cam, pedestal -mounted rocker arms that are retained with cap bolts. Two types of heads where made they were the 2V and 4V. The 2V heads have open chambers with rounded ports, while the 4V has quench combustion chambers with larger rounded intake and exhaust ports. A 351C Cobra-Jet appeared in ’71 with 4-bolt main caps. A 351C Boss also came out in ’71 with 4V type chamber head with pedestals machined to accept a 302 Boss type valve train and mechanical cam.
In ’72 open chamber heads were used with a flat top piston and the name changed to 351C HO. The 289/302/351 engines use a front cover and water exists the intake manifold face of the cylinder head through the intake manifold to the radiator. 351C/351M/400 engines do not use a front cover instead the block extends out to cover the timing chain and water exist the block face. The FE engines are the 390/427/428 engines and are different from all other Ford engines. The 390 is set up basically the same as other engines but nothing interchanges with them. The 427 engines are overhead cam and are extremely powerful sincewise they were used in AC Cobra’s.
In ’64 a 427 could be ordered over the counter and had 625 HP stock. The 428 isn’t much different but is not overhead cam. The last of the Ford engines are the Big Blocks 429/460. 429’s were available from ’68-’73 and named Cobra-Jet, Super Cobra-Jet, and Boss. Basically the 429 was a wedge engine with hydraulic cam, 2-bolt main caps, and 2V or 4V carbs.
Cast iron rail rocker arms were mounted on non-adjustable, positive stop studs until ’72. Then shared the same mounts as the Cleveland. The 460 is a stroked 429. The CJ had a hotter cam, larger carb, bigger port heads and valves. The SCJ had 4 bolt mains mechanical cam, adjustable non-positive stop rocker arm studs, stamped rockers arms push rod guide plates. The pistons are forged aluminum and con rod bolt seats are spot faced.
The Boss had aluminum heads and hemi combustion chambers. This is all about auto manufacturing since everything is machined in some way on engines.
