hi all. after some help please. just building my rb30 ozzie lump up..plastigauged it all.mains & big ends .50 so all is well. trouble is the centre main was tight to press in the block and cradle and when i put the crank in the cradle on the bench there is endfloat, when i put the crank in the block without the girdle there is endfloat. all good so far when i tighten the girdle with the crank in place the endfloat dissappears to zero. any ideas?. shells are acl for an rb30e engine, cant remember from last rebuild the centre main being soo tight to push in the block and girdle?. bernie uk

p.s what acl part number should i have on my box for rb30 mains. also are there different width shells. i know endfloat gap is crutial what would you recommend clearance wise for endfloat.thanks rob.. p.p.s engine is still in bits so can do what needs to be done.
