OK. Well, umm, I'm trying to prevent vapor accumulation in the tank
and percolation in the lines on a mild EFI conversion.  Not going to
say diddly about blown engines, as my bank account and I are working
up to that level of performance.  

I also believe that higher temps are better, and I'm using ceramic
coatings in my daily driver where I run 10.5:1 compression with pump
fuel.  The aspect I was addressing is more of an issue in daily driven
vehicles, especially those which will be used in towing.  It's mainly
a reliability factor.  

I've thought about building a 348/355 for a while now, but I think I'm
going to save up for a rocket block and build a SB 396 (to go with the
SS emblems on a recently acquired 67 Chevelle).  Maybe between then
and now I'll get to try forced induction.  Hmm... There's a Detroit
8-71 in the shop right now.  If I can find a way to get the blower
without them realizing it's gone.... ; )
