Big Block Radiator Hoses

From my response to your question in another thread:

What I originally did was go to a parts store and order up a couple of different hoses for a B or C-Body application with big block. Test to see which fit the best and return the unused.

It's been a long time but I believe the upper may have been a Gates 20875 or Dayco 70352 and the lower a Dayco 70592 or 70369 (Maybe Gates 20558 or 20630). The latter of the two Dayco has tighter bends. Depending on what radiator you're using (these would have been for a stock type 22") some will fit better than others but in all cases some trimming to one end (usually radiator) needs to be done. I do it on a table saw for a nice clean, square cut.
