Lawrie:
I am wondering what kind of gas your customer was using that had so much
pinging. I have a Pierce Manifold cross-flow alum. head on my street/track
B and recently did a compression test. Found I had from 182 - 185#
compression. I don't get pinging except under rare circumstances. And, I
normally just run 93 octane pump gas. Once in a while I'll put a few
gallons of 110 race gas in.
