One other thing to keep in mind while you research, the ECP radiator uses cores that measure 1.25" ea. Most radiators out there advertise 1" cores that are a tad smaller, mine are in my Howe, 7/8". My opinion 3 1" cores stuffed into a 3 or 3.5" radiator would be tight picking up heat from each core around it. 2 1.25" cores in a 3" radiator leaves more room for cooling. Just my opinion and something to think about.
