They left plenty of room in the engine for future expansion. They also appear to have intended to manufacture a V12 on the same tooling as that 5" V8. Does anyone know anything of this project?
That would have been 3.75" bore and 3.25" stroke. Hard to imagine building a 4.7 liter engine which would weigh 710#. The smallest Packard V8 actually built on the 5.0" bore center was the '55 320" or 5.2 liters. Since it cost the same to build as the larger versions, it made less than no sense and was discontinued.The original displacements intended for the V-8 and V-12 were 4.7 liters and 7 liters, both using a 95.3mm bore, and an 82.6
