[Shotimes] Q on installing pistons

[Ian Fisher]

yes and yes

3.0 overbored to 3.2 using 3.2 pistons.

I just installed 2 more pistons and everything seems
to be ok so far.

I'll prob finish the other 3 tomorrow.

It's funny how a rod bearing half can snap into place
and seem to intially fit but you can finesse it some
more and it actually fits better. The trick (I am
finding out) is the make sure the oil hole lines up
with the oil hole in the rod. This is tricky too since
that hole in the rod is at an angle and it can look
"correct" from some angles and not from others. 

I am probably making this harder for myself (always
second guessing what I am doing) but since it is my
first build, naturally I am a bit nervous.

thanks to everyone for their help so far!

Ian
