A little more info on radiators.  I run two 86 Caprice evaporator cores in
parallel.  I have temp probes on the exit lines from each core, and they
seem to share the load almost equally.  Temp drop with 90+ degree OAT is
10-15 F, and now in cooler weather, sometimes I see a 30 F drop.

Also, I recently re-plumbed my system (to allow for an intake mod) and
installed a stock thermostat.  Warm-up is now much faster (duh!).  I cut up
the stock water exit and welded it back together such that it stays under
the cowl.  I was told that the aluminum casting material was basically
un-weldable due to all the impurities, but my neighbor is a TIG aficionado
and was able to do a nice job on it after some experimentation.  (By the
way, this is also the same guy who won the Copperstate race from Apple
Valley, CA., in his Polen Special. He averaged 258+ KTS on 180 HP.)
