http://www.homemadeturbo.com/forum/index.p...99050#msg399050 i stumble across this when looking for the block posting article. what do you guys think? to me it sounds like a fill-in block guard. also, some tuners when they hone the block, they put a rig that simulates as if the head was bolted and torque down because the cylinders arent actually round. well if you were to fill a block without using that rig, wouldnt that mean the cylinders have to be re-honed after filling?
