I have 2 310T oil cooler blocks both out of 1855's.
one has casting # 221520 165101A and 422. I believe
this one is newer. It had the late cam # and bigger
turbo lines. The other is 165606A 221520 and 8297.
I noticed differences in the oil passages and relief
valve. What other differences are there if any?
Thanks.
