Quick engine question...
Define "Comp Height" ... in relation to the specs of pistons.
The only thing I can come up with is the height of the piston at which it has reached it's maximum compression ... ie the TDC position of the piston. Anyone know?

Re: Quick engine question... (Glock'94)
Comp Height is called Compression Height. The Compression Height of a piston is the distance from the center of the piston pin hole to the deck or top of the piston (excluding dome if any).
Here is a diagram from my good friends at Ross:

OH yes and in general you are looking for "normal" or zero. Less will mean less compression. More can mean a piston hitting the flat porion of the head unless the shop you have taken your block to has checked it thoroughly...
