spun a bearing on the last motor. put a new block in with the same head,now it smokes it butt off. i replaced the head gasket and new aebs head studs. timing is on and i did a compression test 110 across the bord. is it the head or the block. the compression seems to be really low. help me please

 

sounds like you got screwed and bought a motor with bad rings

 

that motor should prolly be around 210 all 4, just my .02
