[QUOTE="03SVTCOBRA10TH, post: 8258701, member: 11983"] #5 and & #7 don't sound right.... this is and iron block correct?? I usually bore match each cylinder to a specific piston and leave 0.003" of material left from final pistion to wall values for plateau honing. Here are the steps I use. FORD 4.6L V8 PLATEAU HONING RECOMMENDATIONS Ford has developed a specific procedure that engine rebuilders can use to duplicate the OEM plateau cylinder bore finish in Ford 4.6L V8 engine blocks (which are diamond honed at the factory). The honing equipment specifications are for a Sunnen CV-616 with Sunnen MB-30 honing oil as a lubricant, but the basic procedure can be adapted to any honing equipment. Prior to honing, Ford recommends cleaning the block (if heat is used, the temperature must not exceed 750 degrees F) and inspecting the block for any defects. The "semi-finish" operation is performed after boring or rough honing the cylinder bores to within .003 inch of final oversize. Spindle speed 170 rpm Feed rate setting #4 Stroke length 5.250 inch Stroke speed 57 SPM Top over stroke 3/8 inch Hone head CK-3005A Stones C30-A45-81 Stone length 2-3/4 inch Stock removal .003 inch Once the semi-finish step is complete, the plateau operation is performed with the following settings. Ford recommends hand feeding the stones using the crown wheel to maintain a load reading on the load meter of between 20% and 30% (30% is optimum). The load must be maintained for 30 seconds. Spindle speed 170 rpm Feed rate setting #1 Stroke length 5.250 inch Stroke speed 57 SPM Top over stroke 3/8 inch Hone head CK-3005A Stones C30-C03-81 Stone length 2-3/4 inch Stock removal .0001 inch Did they match each bore to a specific pistion??
