Can a single port engine be  changed/adapted to use a twin port oil cooler set up?

I've got an engine which I believe was originally a single port, but is now twinport. The fanhouse is single port (not doghouse) and the cooler is outside the fanhouse!!!!!
Won't be running it like that.

The engine number is D 1300751.

You'll need to use conversion oil cooler seals and a dog house fan housing.

A "D" code engine is a 1,200 engine, which were all SP engines. However the later 1,200 engines used the later AS41 cases which was a twin oil relief case that is used on all the TP engines, which use the dog house fan shroud. So you can change any t1,t2,t3 engine into anything you want basically but later cases are better because they have bigger oil passageways for performance engines
