My new engine has shown me I need a bigger radiator. I'm looking for sugustions on how big.
The old radiator is for a Ford Ranger II, it is 18" x 18" x 1", one row core, alum core and plastic tanks. It worked good with my old engine, but it only had 10:1 comp, iron heads and "loose". I could make three 1'8 mile passes, back to back to back and would actually cool down going back to the staging lanes.
New engine has 13.5:1, alum heads and is "fresh". I pull out of staging lanes at 140*, do burn out, make pass and back to the trailer its 195* and takes 10-12 min to come down to 145*. My concern is to not put more than is needed, because of the weight of the water in the radiator.
Anyone have any ideas?

Thanks, Brian
