hey all i was just wondering if a four core radiator fits in a round nose because some one told me they dont fit is that true???????

They do fit but you may need to snip the radiator shroud on the body a bit at the bottom. I even had to do this to fit a Pommy 3 core... which then fell apart 3 months later.
Hey, an original Oz 3 core (which have 16 fins/inch) is hard to beat, my 1360 never overheats and it has over 125HP.
Pommy 2 core is OK, but no better. So why spend a fortune- just get yours overhauled properly at a radiator shop.

well u c it aint my car it is my bro car and it has heating trouble we have a fresh air heter under the bonnet and a normal radiator in (standard one) and it still runs very hot when driving it around town. so u recon get the standard radiator recon ????

Yeah just go get it taken apart, acid dipped, rodded out and reassembled.
The cost is probably $90-100.
It'll fix it as good or better than a new $270 2 or 4 core.
Clean the heater core out too, some cleaner will do it.

While you have the radiator out, take out the thermostat and flush the block with high-pressure water (from the garden hose will do) in both directions, then run some radiator cleaner through as well to get as much of the rust and crap out as you can.

When you have it spotless and refill with the radiator, use a good coolant. It's not quite as effective as plain water at conducting heat, but will keep the water jacket from rusting up and clogging again.
