I am still having heating problems, my water temp wants to go out of sight. I switched to Edelbrock alum heads and water pump. I have a four core B&B radiator that checked out fine. I have replaced two thermostats and berped all the air out of the system at the manifold I have ordered a 2400 cfm fan to replace my other fan and am considering ordering a two row aluminium radiator. Running out of money and patience. Basically, just damn pi__ed off right now. Anyone have any thoughts on my delima?

Hi Clois,
One thing to consider about alloy(aluminum) radiators and Copper units. The copper radiator will have a better heat transfer rate then the Alloy unit.
We use alloy units in all of the JBL cars as they are much easier to have fabricated by various vendors in the size and shape that we use. If I could get a copper unit made at a reasonable cost, that is what we would use.
Therefore, If your current radiator has enough surface area to provide the required heat transfer, a alloy unit with the same surface area will not improve your cooling and will in fact be a bit worse.
I would look to other problems in the system.
