Video: How the ZL1 Engine Block is Honed
Posted by: admin In: Main ()
Cool video showing how the ZL1 engine block is honed using deck plates to simulate cylinder heads being torqued on the block. Why go through this process? As forum member Lonny Doyle explains:
When you torque the cylinder heads and main caps onto the engine block it causes the cylinders to distort, so if you were to hone the block without deck plates and the main caps installed the cylinders would measure round and straight until you assembled the engine.
Once you installed the heads and main caps the cylinders would no longer be round and straight. So to prevent this from happening they simulate the engine as if it were assembled while they hone it by using deck plates.
