Set of 8 Forged Pistons - Ford FE 427ci - Brand New
Piston Skirt diameter 4.272 inches (stock FE 427 ci bore 4.23 inches) requires .042 overbore
Compression Height 1.450 inches
Piston Dome Height .350 inches
Net Piston Volume +8.59
Compression Ratio 10.83:1 (using 76cc combustion chamber cylinder heads)
Stroke 3.980 inches (same as FE 428 ci crankshaft stroke)
Connecting rod length 6.49 inches (same as stock FE 427 & 428ci engines)
Deck Height 10.150 inches (stock FE 427ci 10.170)
Piston Pin Diameter .990
Total displacement using the above combination with a .035 thick head gasket calculates to 456.38 cubic inches. Block deck machining would be required to achieve the 10.83:1 compression ratio. The compression ratio would be 10.36:1 if the standard FE block deck height of 10.170 remains the same using the .035 cylinder head gasket.
These pistons were built for the Edelbrock 76cc combustion chamber FE cylinder head. There are two sets of four each, for the FE in-line valve configuration IE-IE-EI-EI. A Carrol Shelby aluminum FE engine block was to be used for the build. The customer decided on supercharging after the pistons were ordered and custom orders cannot be returned, so we are selling these.
