Manley Piston Identification
Have a set of Manley High Comp 12:5 to 13:0 ratio pistons. I measure them perpendicular to the piston pin bore at 4.045 ...
When I invert the piston I see an upside down triangle with the letter "T" at the apex.. Pins are retained by circlips.
Anyone have an idea of what the "T" in the triangle is, and what is the CR of the pistons with the various stock Chevy 60s - 70s combustion chambers?
Thanks!
T
