Thread: Dial Bore Cylinder Question

Tweet

When you are thatclose on the specs-the cylinder wall surface finish is probably more important than that little bit of clearance-
Most chevy bores are stated at .001 over the nominal size------4.001, 4.021, 4.031--------

You need to mearsure the pistons to determine there sizes before worrying what the cylinder size is. Also, if you don't have a dial bore setting guage--use the same mike to measure the piston that you use to measure/set the dial bore guage------

and also the use of a torque plate will change/alter the cylinder shape the same as if a head was torqued in place and this is reason race engine builders will use torque plates and temperture conttrol to get the most accurrate results
