Could anyone tell me the best way to go about cooling my 1330. Just rebuilt mildly hot engine. It has a four blade fan and a new 2 core radiator. I was thinking a small thermo fan under the left guard to help suck some heat out? Has anyone else had this issue?

Put a Clubby heater core behind the grille. Hook into heater water circuit.

First, I would be checking for blocked cores in the radiator. You would be really surprised how much scale comes loose from the engine blocks water jackets after an engine is rebuilt.

Already checked that. I was hoping someone with a re13 cam had some insight into this as that is the cam I'm running.

I have had 3 motors (1310, 1412, 1360) in my car with no overheating at all. All 3 ran an RE13 cam. However it still has the minimatic heater up front which works like adding a heater core behind the grille. Radiator is stock Mini K/Mini matic/Cooper S 3 core. Reconditioned.

I never had a problem with the RE13, even after putting a supercharger on it -

radiator sealed around the cowling so air can't get past without going through the radiator?
ignition retarded?

thanks , if I was to put the heater core behind the grill, would it be very noticeable?

You can hide a lot of stuff with matt black paint

Spray the core a thin coat of black and you won't notice it.

Have a look just recently in the "what did you do on your mini today" thread and you'll see JPrior2912 has just installed one and added some pics.
