Description
Lots of research and devepoment went into refining these piston kit combinations. Over 40 years of understanding and testing has brought this amazing combination of products together to yield you the best mechanical reliability, horse power and torque output. We start with our Olds Performance Product anti detonation chamber design and incorporate that into these forged 4032 full float Diamond Pistons. We then add a ultra-fine micro polish set of HD wrist pins which get secured in place with our double spiro locks. A set of H beam connecting rods which are bronze bushed for full floating wrist pins and incorporate the ARP 2000 series upgraded bolts. Pin oiling is also a standard feature that is incorporated in these connecting rods. Each 4340 chromolly H beam connecting rod is precision honed for an exact tolerance that is plus/minus .00005 on the big end. When only the best will do, we incorporate this premium Total seal ring package which consist of their gold power flex vent expanders for the ultimate in oil control. Contact us for the labor to pin fit if you’d like Olds Performance Products to do that proceedure. A well in depth Pin fit proceedure can be found on our you tube channel Olds Performance and Machine or on or facebook social media page Olds Performance and Machine. This kit is for a .040 over bore 455 engine from the years 1968 through 1976. 10.5 compression.
