                        These pistons can be used on combination with either 274 duration or dual pattern 280/274 duration cams. (415 lift) Mr.E's Cams.

                        For Sport Clearance, Oem Durability use or buy the 274 duration cam, if you want a more responsive, autoX engine use the Rally clearance with the dual pattern 280/274...

                        Sport Clearance is for 170k+ miles engine...
