Chrysler Golden Lion V-8 specs: 413 ci (6.8L) 8-cylinder, 4.188 x 3.75 in (106.4 x 95.3 mm) bore and stroke, 10.1:1 compression. Rated 350 hp, 1959.
The Chrysler Golden Lion V-8 is oversquare — the 4.1875" bore exceeds the 3.75" stroke by 11.7% — a layout that favors airflow and RPM over leverage at the crank. The 3.75" stroke puts mean piston speed at 4,000 ft/min around 6,400 RPM, which is where a production bottom end is generally considered at its limit. Each of the 8 cylinders displaces 51.6 ci (846 cc).
10.1:1 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 2 engines in the Chrysler 413ci family, all of them 413 ci — the differences between them are in compression, heads and rating, not displacement.
