Ford developed the MEL ("Mercury-Edsel-Lincoln") engine series for use in their line of Mercury models from 1958 through 1967. The MEL also replaced Lincoln's unique Y-block design. These engines were produced in Lima, Ohio at Ford's Lima Engine plant. They were replaced by the 385 series engines.
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 Big-Block 348 combustion chamber, also introduced in 1958, and the later 409. 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 which were introduced at the same time.
The MEL was similar to the Ford FE, with the same oiling system, bolt patterns, and valve stems, but was even larger. The main bearings were 2.9 in (74 mm), while the rod bearings were huge at 2.6 in (66 mm).
The ONLY Ford that a MEL was in was the 1959 and 1960 T-Bird, it was a 430.
The largest is a 460 that can be bored out to 4.625 to making it a wooping 806 and the 351W bored out to 4.125 making it a 454. But these are custom motor that make 3,000 plus hp and will run you between $30,000 and $40,000's. (Flatlander Racing)
Well, I've heard of 614s before. I think it's a bored 460, but I may be mistaken.
However, boring out your motor will affect HP more than torque. If you want more torque, go for more STROKE. However, piston life is decreased with more stroke.
whats the largest ford engine?
