★ Professional oversize piston set for restoration and engine overhaul. Requires precision boring of the cylinder block to +0.040" by a specialised machine shop.
Application
For 230 ci (3.8 L) six-cylinder L-head engines. This engine version was used in various WW2 Dodge military vehicles with T214, T215 and T223 engine specifications. Oversize pistons are necessary when cylinders need to be rebored due to wear during an engine overhaul.
Installation notes
Cylinder block must be professionally rebored to exactly +0.040" oversize by a machine shop. Check connecting rod bearings and crankshaft for wear. Piston ring end gap and piston-to-cylinder wall clearance must be set according to specifications. Use new piston rings (sold separately). Assembly requires expertise and specialist tools.
Compatibility
Only suitable for 230 ci (3770 cc) engines, NOT for 218 ci version. Bore and stroke must match: 3.250" standard bore + 0.040" oversize = 3.290" final dimension. Always verify actual cylinder dimensions after reboring. Not compatible with standard-size piston rings — use +0.040" oversize rings.
Historical context
The 230 ci L-head six-cylinder engine became standard in Dodge WC-series vehicles from mid-1941 onwards and produced 92 bhp at 3200 rpm. This robust engine provided reliable power for thousands of WW2 Dodge lorries well into the post-war period.
