My big end bearing eat itself after a 10k engine build by RCM to the owner before me,only had bigger pistons put in!! When I questioned it Olly said the owner was on a budget!! Totally ripped off!! So make sure you go to a proper engine builder, I only use Three arches in Cardiff,Dean done my build on rb320 and running 410/410 bhp torque, and powerstation mapped it. Good luck bud
