Lincoln 462 MEL V8 specs: 462 ci (7.6L) 8-cylinder, 4.358 x 3.902 in (110.7 x 99.1 mm) bore and stroke, 10:1 compression. Rated 340 hp. OHV.
The Lincoln 462 MEL V8 is oversquare — the 4.3583" bore exceeds the 3.9016" stroke by 11.7% — a layout that favors airflow and RPM over leverage at the crank. The 3.9016" stroke puts mean piston speed at 4,000 ft/min around 6,150 RPM, which is where a production bottom end is generally considered at its limit. Each of the 8 cylinders displaces 57.8 ci (946 cc).
10:1 on iron heads is in the range that usually runs on pump premium; iron holds heat, so treat it as the less forgiving side of that range.
It is one of 3 engines in the MEL family, the largest at 462 ci. Factory fitments include the Lincoln Continental, Continental.
