This 5.0L (302-ci) nodular iron “2ME” crankshaft has a 50-ounce offset balance. Thousands of 351C engines have been raced over the past 40 years with cast cranks without consequence. Also, the Hi-Po’s slide-on steel plate counterweight was used to balance the additional weight of larger 3/8-inch rod bolts. The 255 crankshaft is approximately 9 pounds lighter than the 302 crank. Notice the high dome for 11.0:1 compression. Make sure you have plenty of material around these bolts before making this modification. The C3AE Boss 302 rod was also used in 2.3L overhead-cam turbo fours used in the Mustang SVO, Mustang GT Turbo, Capri RS Turbo, Thunderbird Turbo Coupe, and Cougar XR-7 Turbo during the 1980s.

The 351 Windsor’s nodular iron crankshaft has a 3.500-inch stroke and 3.000-inch main journals with a “3M” in the forwardmost counter-weight/journal. Small-block crankshafts received Ford casting numbers later in the 1980s. ← Older Post In your search for a good 5.0L “2MA” or “2ME” crankshaft, don’t mistakenly buy one for the 255-ci (4.2L) engine, which looks the same externally with the same 3.000-inch stroke, but has hollow rod journals for reduced weight, which also compromises strength. Although it has a 28-ounce offset, it is counterweighted differently for the same reason it has a slide-on crankshaft counterweight. The bottom oil rings carry oil down the cylinder wall and back to the sump.

If you’re building a Boss 302 to go vintage racing, you don’t need to spend a fortune on a set of C9ZE-G cap-screw rods because the aftermarket offers a wealth of more affordable hardware for Boss 302 and 289 High Performance engines. Ford dished pistons to control and reduce compression. Most of the time, compression was controlled by the amount of dish, if any, in a piston. A 289 High Performance crankshaft is identified the same way plus having the Brinell test stamp. Hank the Crank began producing steel Cleveland cranks in 1974 for drag racers. The aftermarket has followed suit with a great selection of cast, steel, and steel billet Cleveland cranks. When installed properly, the one-piece seal is virtually leak-free for the life of the engine.

The one-piece seal is a large-diameter seal with a garter spring reinforced lip. The second compression ring, also known as an oil control ring, both seals the combustion chamber and carries oil up the cylinder wall. This is a 351W crankshaft (E4AE-BA) with the one-piece seal. On the left is a “2ME” crank for the 5.0L engine with a one-piece rear main seal. The 351C, including the Boss 351 and High Output, was never fitted with a forged-steel crankshaft. Terms | Privacy, Rotating Assembly Parts Interchange for Small-Block Ford, FORD SMALL-BLOCK ENGINE PARTS INTERCHANGE. Your first line of defense is knowledge of small-block Ford rotating parts and what works best.

It acts as a shock absorber, limiting crank twist and rebound.Â. Each has its own bellhousing.Â. It is different than the nearly identical Boss 302 dampener because of its counter-weighting. Although other Ford V-8 engine families had both cast and steel crankshafts, the 335-series engines were produced in cast only. Although you should look for the Brinell test mark, which means the crank has been tested for hardness, this mark is difficult to see and is little more than a small dent.
