Title: Truimph
Post by: m.c.112 on August 30, 2009, 06:07:40 PM

Hi,
    I have a 1969 T100, and was wondering will the pistons out of a 1966 model work in it...Or is there a difference???

The head combustion chamber shape changed drasically in 1967, and the pistons became much more high-top. The earlier pistons would work but give a low (possibly very low) CR. Should make for a very gentle engine, but not exactly in the Daytona class.............
