So, I=E2=80=99m putting together my car with a fresh engine.  With a new =
engine, I almost always spend a few hours on a local chassis dyno - seat =
the rings, set the timing, check performance, play with carb jets, etc.  =
Way better than showing up at an event with adjustments not made or an =
engine that blows up on the first run.

Anyway, I have a new quartermaster 7-1/4=E2=80=9D clutch assembly and =
flywheel that I would like to put in. However, I have to slip the clutch =
a lot to get the chassis dyno spooled up, and if I do 5-10 pulls, =
that=E2=80=99s a lot of clutch slipping.  Am I going to toast the new =
little guy?

The alternative, which is of course not very attractive, is to put the =
full size flywheel/clutch assembly in, do the dyno runs, then pull =
everything out and swap it. Basically an engine/trans pull, as swapping =
a flywheel with the engine still in the car and the transmission out =
just sounds painful.

Thoughts?=
