Information About

Ford Mel Engine




All MEL engines had wedge shaped combustion chambers formed between a flat head surface and an angle milled block deck, with the piston top determining the compression ratio and combustion chamber shape. Similar to the Chevrolet 348 combustion chamber, also introduced in 1958, and the later 409. Although unlike the Chevrolet, which had staggered valves and scalloped or M shaped valve covers, the MEL valves were inline with shaft mounted rocker arms like the FE model Ford engines.


383


The 383 in³ (6.3 L) Marauder was the smallest member of the family. Produced from 1958 through 1960 , it was only used in Mercury vehicles. It used a 4.3 in (109.2 mm) bore and 3.3 in (83.8 mm) stroke. Output began at 312 or 330 hp (233 or 246 kW), both with a four-barrel Carburetor . 322 hp (240 kW) was the only output for 1959 , and power dropped to 280 hp (209 kW) for the final year.


410


The least-common MEL engine was the 410 in³ (6.7 L) E-475. Bore was lower at 4.2 in (106.7 mm). 10.5.1 compression, a Holley four-barrel carb, and hydraulic lifters pushed out 475 ft.lbf (644 Nm) of torque. This engine was only used in the 1958, Edsel Corsair and Citation .


430


The 430 in³ (7.0 L) engine was produced from 1958 through 1965 . It was also used in Ford Thunderbird s and was commonly referred to as the "Bulldozer" of the MEL series engines. The Super Marauder used three two-barrel carburetors. The 430 was bored to 4.30 in (109.2 mm) (similar to the 383) and shared the 3.7 in (94 mm) stroke of the 410.

The compression ratio started at 10.5:1 for 365, 375, and 400 hp (272, 280, and 298 kW), but was reduced to 10.0:1 in less than a year. These 1959 engines produced 345-350 hp (257 to 261 kW), but power was down to 315 hp (235 kW) for 1960.

New pistons and a four-barrel carburetor were added for 1963 . 10.1:1 compression brought output back to 345 hp (257 kW).

Applications:


462


The 430 was replaced by the 462 in³ (7.6 L) engine in 1966 . Bore and stroke were entirely different at 4.38 in (111.3 mm) by 3.83 in (97.3 mm). This engine was fitted with hydraulic lifters and a four-barrel carburetor, and the large torquey engine was used in large passenger cars. Production ended after 1967 . The production facilities in Lima were converted to produce the new Ford 385 Engine family.


REFERENCES


the 462 MEL engine was only used in Lincoln Continentals, from 1966 until mid-year in 1968 when it was replaced by the 385-series 460. the 462 had a carter AFB carb, the 460 had a ford carb. the MarkIII for 1968 had only 460s and never had a 462.
