This time around, we are concentrating specifically on honing the cylinder bores ... rules that allow a maximum engine displacement of 358 inches for both small block Fords and Chevrolets.

Typical bore dimensional variations For purposes of this story, four small ... the hot-hone process closely approximates the dimensional environment of a running engines cylinders.

You're looking at a process called extrude honing ... into each individual cylinder, into the combustion chamber past the intake valves. If we increase the airflow to an engine, the engine's ...
