Bearing to use on VR4 block stroker

[samson_cck]

Hi all sifu there,

hope you all can help me on my built, i wonder what bearing to use on my stroker built. i have VR4 6 bolt block, 4g64 7 bolt crank and i want to use back vr4 conrod. for main bearing any different for 6 bolt and 7 bolt? as i know the crank journal for 7 bolt are narrow so if want to use the VR4 conrod it need to be shave on the conrod big end. in the case what bearing i should use for conrod? still VR4 or Evo bearing? on the other hand, how about main bearing? pls advise me as i thinking to get ACL or king bearing. thank in advance.

the bearing size depends on which conrod you're using rite...

a 7 bolt crank wont fit a 6 bolt block

Yea, thank for info... after buying the 7 bolt crank only know the VR4 wont fit. so now was selling the VR4 engine then buying an EVO engine.

get a 4G64 block, better and cheaper solution :D
