Starting with a new GM LS2 block HPR has designed this stroker kit to get the most displacement for your dollar.  The ever popular '402' has been a staple of late model LS engines for years.  The HPR 402 uses solid quality forged components then inspects and machines to our exacting specifications for a long lasting engine you can count on for years to come.
