Uhhh. wrong answer. You've got to fit the piston to a specific bore size, not just the mid point of the road from 6 different choices.
Also, here's a copy of Terry's email
"Sorry Aussie but....
They were bought as a drop in for the 2.5L engine - I
got them to suit the nominal 2.5L bore.
...is the wrong answer...they would make them all 'mid
point' i.e Grade 2.....You MUST be very specific with
ALL dimensions when you are an engine builder...you
can always remove metal but you can't put it back!!!!"
Thanks,
Rick
