spun bearings usually leave the crank structurally un-sound for building power. If you have a good crank, then use his block. Make shure the Main bearings are the same. Early H22 have 55mm mains and H22a4 (later) have 50mm mains.Originally Posted by omar
Spun bearings don't affect the block strength.




I need to find another h22 block to do this build. Boosted lude has one for 150 with a spun bearing. How much damage has been done to the block? What prep work should i do to prepare a spun bearing block for all motor setup?
