Icon Pistons IC10019-080 Fits SBC 350 Flat Top 10cc 4V Bore 4.080

's FHR (Formed Head Relief) pistons deliver quality on a budget. FHR pistons have valve reliefs that are formed into the piston as the forging blank is pressed into the die. Many of the FHR dome pistons feature a solid dome. This gives engine builders the flexibility to machine the dome to their desired compression ratio. FHR pistons are 11% silicon which means they can be installed with tighter piston to wall clearance. In addition, the use of 4032 aluminum decreases the friction created during engine operation, this results in extended piston life and reduced wear.

Mini grooves allow an overheated pistons to transfer heat to the wall
