[Fot] EGT's again

[Tony Drews]

I run about 6" from the flange.  I run 1400 in the 2nd half of the 
straights and have never seen any evidence of melting on my forget 
pistons.  I suspect that thinner cast pistons may be more susceptible 
to melting.  I also run 110 octane leaded and about 32 degrees of advance.
