RE: 273 Swapping Sides on Pistons

[Jeff Adams <ledman_70@xxxxxxxxxxx>]

When I built the 426 wedge for my 64 Polara 4 years ago I used any tips 
from Don's "Old Reliable" I coud, and one of them was to turn the 
pistons (stock 10-1) 180 degrees. The engine has about 3200 miles on it 
now without any problems, but I can hear some noise on the road. 
However, I think it's something else rattling a little, not the pistons.
