Subject: [Tigers] radiators and heads etc

I have a 302 bored to 330 and it doesn't like slow running in the heat.  I am removing the engine this winter and could make some changes if warrented.   Will  clean up the engine compartment,  throw out bearing, clutch etc.  

Do aluminum heads run cooler than cast iron?

 Would I be well off to rebuild my very  old radiator  (stock) with copper or aluminum?  

   .     Russ -       [email-masked]         Thanks again.

When I built my 302 (bored, stroked, blueprinted, etc) I added TrickFlow (aluminum heads) and an aluminum radiator.  They make all the difference.  My Tiger runs at 180 now - even when it's in the mid 90s outside.

Have you achieved 330 with just boring and not stroke change??? Normally a
332 is done via stroke as well...

Wondering if you have created same issues as overboring 260 and 289 to
far.... They overheat as the bore walls get to thin and close to water
jackets
