Question Retrofit Cooling sys. ?

I'll try and make this short but it's a big?
69 chevy caprice. New 350 Crate engine with headers, preformer intake, HEI ignition,and a little bit hotter than stock Cam, and A/C.
My problem. I'm not sure that my 33year old pluged and corroded radiator is up to the task of cooling. Engine size and AC are stock, But will the power add too much heat?
I'm thinking of going with a new alum. 2x1" tube rad. that's 27x19" and then adding a seprate trans cooler about 8x11", and maybe a engine oil cooler? with two 2500cfm electric fans?
does this setup seem good?, what about the Engine oil cooler?, will I have too many coolers and not enough air flow? any advice would be great

I wouldn't go to crazy. I've upgraded a couple small blocks over the years and usually with a simple cam, carb., manifold, and ignition upgrade what I usually try and do is first upgrade the radiator. If I had a two core I'll go to a three or four core to increase coolant capacity and radiator efficiency. A good fan and shroud is also important. Causing your engine to sustain higher R.P.M.'s (ex. changing from a 2.73 to 1 rear to a 4.10 to 1 rear) would be a different story, but it doesn't say you did that. A little help in the cooling dept. never hurts but from what you described you shouldn't need to go crazy. Also a temperature gauge goes a long way.
