Title: radiator hose sizes:
Post by: Stewart G Griffin on June 20, 2015, 04:03:01 pm

Would anyone happen to know what the radiator hoses sizes are?   I.D. and O.D.   for upper and lower radiator hoses for a small block?

It looks like 1.50" both sides for the upper and the lower is 1.75" at the radiator and 2" at the water pump.  i'm in the middle of figuring everything out right now.

Hmmm.....it looks like the 4.3 radiator hoses WILL bolt up to the v-8 radiator. :)

Not perfect but good enough to get it running.
