Dodge TBI specs: 360 ci (5.9L) 8-cylinder, 4.00 x 3.58 in (101.6 x 90.9 mm) bore and stroke. Rated 190 hp, 1990–1992. Used in the Dodge D-Series Pickup. OHV.
The Dodge 360ci (TBI) is oversquare — the 4" bore exceeds the 3.58" stroke by 11.7% — a layout that favors airflow and RPM over leverage at the crank. The 3.58" stroke puts mean piston speed at 4,000 ft/min around 6,700 RPM, which is where a production bottom end is generally considered at its limit. Each of the 8 cylinders displaces 45.0 ci (737 cc).
It is one of 13 engines in the Dodge 360ci family, all of them 360 ci — the differences between them are in compression, heads and rating, not displacement. 3 factory variants share these dimensions, rated at 190 hp across 1990–1992.
