Flat top pistons for the 460 Ford will range from 10.4:1 in a stock stroke motor to 12.5:1 with a 4.500 stroke version. All are manufactured on application specific 2618-t6 forgings and have valve reliefs suited to either OEM valve locations or the SCJ/Kaase head. AFR, A460 and C460 heads can also be accommodated at no additional cost. All 460 pistons have an exhaust pocket added to eliminate piston to valve clearance issues on the exhaust side.
