^if he's going with the 81.5mm's then the block will have to be bored .5mm bigger. i'd say take the block and crank to a machine shop, get it bored and have them polish the crank. and personally i'd go with Clevite77's or Calico bearings. also have them shot peen your rods, after which they'll have to resize them and press in new bushings but it'll be worth it on a boosted build.

and i wouldn't recommend Eagle anymore, we've been having problems with there products. we've gotten two cranks in the past month that have been soft (not heat treated right) and they ended up spinning bearings.
