Mopar 360 /408 Small Block KB 745 Forged Pistons 4.030 Bore for 4” stroke – Used

Description

I have a very nice used set of Keith Black Forged dished pistons and pins for a 360 or 5.9 liter Mopar engine using a 4.000” stroke crankshaft part # KB 745. These pistons along with a 4.000" stroke crankshaft will produce a displacement of 408 cubic inches.
Pistons were used for one summer as a mild street build. Engine was rebuilt the following summer into a bracket racing focused application so these pistons are no longer needed.
Pistons were used for ~ 500 street miles. They have been fully cleaned and the skirts lightly glass beaded. Two pistons had some minor modifications to ensure adequate piston to valve clearance. See two photos. One piston had some skirt scuffing and has been replaced with a new piston.  Pistons fit either Mopar 360 or 5.9 liter Magnum engines with a 0.030 overbore from stock to achieve a total bore of
4.030"
Piston specs are as follows:
Bore 4.030 in.
Stroke: 4.000 in.
Rod Length: 6.123 in.
Piston Style: Step head, with two valve reliefs
Piston Material: Forged aluminum
Compression Height (in.): 1.465 in.
Piston Head Volume (cc): +20.50cc
Wrist Pin Style: Press-fit or floating
Pin Diameter (in.): 0.984 in.
Piston Ring Thickness: 1/16 in. x 1/16 in. x 3/16 in.
Compression ratio with a 65CC chamber, head gasket compressed thickness of 0.040 and installed at 0.0 deck height will be ~ 9.90 to one.  Your final compression ration will depend on the cylinder head chamber size, compressed head gasket thickness and final deck height.
Price is 0 plus shipping cost.  International shipping and local pickup also available.  Shipping will be calculated based on your location which you can check with the calculator.
