I see the norm here is the 86' chevette heater core . I have found this one from a 79 bronco which is 1 3/4" taller and has same size barbs, and cost $3 less.

My question is would the bronco core function better because of the size, or would that hinder preformance with only 1 120mm fan and shroud? (gonna custom make a shroud for either 1 i get )

It might hinder flowrate slightly because it gives the water more tubing to travel through, but not enough to make your temps higher. The added surface area makes up for it easily (and then some IMHO).

I use one from a Taurus, which sounds about the same size, and use only 1 120mm myself. It's always worked great for me (four years and counting).

I have my cpu and northbridge cooled right now. I had to change video cards and with it went my waterblock (epoxied on). The new video card is an all-in-wonder type gforce, so I haven't even tried to look at cooling that yet. It's just a mx440 anyway, not like it's getting super hot.
But yes, I had all 3 items cooled and the temps were the same as they are now with just the cpu and nb.

The only thing about using a core different than the chevette is that you have to make your own shroud. Mine's made from copper sheet and is 2+" deep.

good to hear that. Right now with a black Ice pro rad I cant cool the GPU cus the system cant really handle cpu and gpu overclocks.
As for the shroud I'm picking up a fiberglass repair kit and gonna create my own so thats not an issue

Remeber Bigger is always better if you have the fans that can pull the air through them. I was just given two heater cores, a
10 3/4 x 6 3/8 x 2 1/2 for the CPU and a 6 x 6 x 2 for the GPU and NB. I have two Pelonis Fan model G1751H12BALB 256 CFM @ 55 dBa but I'm using a Nexus 301 fan controller to control the fan speed. I think there around 41 dBa and 180 CFM on each fan.

Bigger isn't always better... If the added resistance from having a huge radiator or two radiators makes your pump work inefficiently it will produce a lot more heat while giving very poor flow.

I was given a Little Giant Pump 4-MD-SC that can flow 550 GPH at 15" and 10.9 PSI, the pump is Magnetic Drive so the pump should not heat the water from what Little Giant Pump Company told me.

Well...with a pump like that (assuming you meant 15' and not 15" :D) I'd say go for it. In this case the extra size will more than make up for the extra length.
