Diamond Pistons Gwatney Performance
  • 4.070″ Bore Piston
  • This piston was modeled after our Standard Compression drop-in piston, but enlarged by .005″ to a 4.070″ Bore

Technical Notes:

  • .040 minimum thickness gasket can be used
  • When milling more than .030 it is advised to check the clearance of piston to the combustion chamber
  • When milling more than .040 it is advised to use a non-extended tip spark plug like the brisk rr14 rr12 rr10 along with Moroso indexing washers to ensure the plug tip is not touching the piston dome

Warning: 

  • These pistons will not fit the OEM 6.098 connecting rods.
