that's what the GT6 has.  TR6 with the stroker crank may be different.

I agree with you, they seem tiny, but I'e been running them for six years w=
ith no issues.  Carillo tells me they are re-usable, though I never thought=
 to record the installed measurements and check against them a year or two =
later.

What I will do when I pull the bottom end apart in a week or two is to meas=
ure the installed length and then remeasure once disassembled.  If they "sh=
rink" as much as the stretch dimension used for installation, they should s=
till be good, i.e., they have not been stretched beyond the elastic range.

The most cost effective thing you can do to your engine is spend a lot of m=
