Well its a older stock 440 so it should be fine with my current 22inch rad ?



I run a mild-build 440 with a 22 inch rad--as do THOUSANDS of others. I do think the system has to be in good shape. Rad must flow well, you want a high flow stat, spring in the lower hose, no underdrive pulleys,fan shroud, GOOD fan, rad support/hood seal. It should be OK.
