what size core should I be looking at on the Jegs site. As for RE, the one they sale will not support my hp. I'm making over 400hp whp. My 3 core brass chills the engine fine however it can't handle the heat load of the condensor when the ac is on. Slowly creeps to overheating point when idling with ac on.
I found this on ebay, sizes seem about right. really hope its a true 3 inch thick unit. Most of the universal 2 cores I'm seeing are 2 1/4 thick. It should fit I just need to make mounts and pump the coolant right
