'67 Barracuda w/360

First off if you are using a 70's 360 then you need to purchase a radiator for a 70 or newer A-body. The later small block motors have the water pump on the passemger side.

The heavy duty 22" radiator is readily available from most parts store. i got one from Advance Auto. You could go with the 73+ Duster 26" wide radiator but it will require cutting out the core support. The 22" one was used for AC use and with a stock 360 should work just fine. My 360 is built up quite a bit and the 22" heavy duty radiator handles my engine just fine.
