[Chrysler300] 300 F: from 413 to 426

[Jim Pristelski <ajp002@xxxxxxxxx>]

Ridge reamers are probably still sold by JC Whitney.  However, my local
machine shop requested that I never again ream off the top ridge of the
cylinders since the reamers often do not remove the ridge uniformly.  The
benefit for the machine shop is that the top ridge centers their cylinder
boring equipment to operate on the original center of the cylinder.   The
original center may be lost if the top ridge is not perfectly or
uniformly removed.

Best, Jim in northern IL

"Back in the day" you could buy a ridge reamer. Would take care of the
ridge without a boring job.
