looks like it's for a v8 the inlet/outlet's are the same as ours except theirs are bigger.. I have read you can convert them, take some welding, but in end u'd rather find a 20inche wide 71+ mavrik for a 250 grab mikes t-stat housing drop in with only trimming.
I'm actually looking for a 24inch wide rad, as that would be the max I can put in my car. but my current rad is still working... for now
