Never had a set of leafs that had location holes for the clamps. In my early years as a drag racer, I tried numerous numbers of clamps and spring clamp locations to modify the way the spring reacted. Sometimes it had noticeable effects.
RJ, I don't doubt your theoretical assessment. However, I do wonder if a painted aluminum part conforms to that, what does the paint/aluminum interface play? Seems only actual empirical testing would give us the answer. I'll just leave my aluminum radiator plain and rely on the tube size, fin...
My point was that the wider tubes allow the wider fins to distribute the heat better. I understand "black body radiation", but I don't think that really applies to an aluminum radiator.
A good starting point is a factory service manual(FSM). Won't be all you need but has much information. Sometimes takes a lot of time to figure out what it is showing you.
When I swapped out the 318 2bbl in the van for a 360 with LD4B & Carter 650, Comp260HE & cheap headers, picked 3 MPG average & 5MPG towing the 5500# race car & trailer. And the 360 could go up hills with no trouble.
My '76 Dodge cargo van weighed about 4600#, I guess more than a '70 Charger 318. My 318 van regularly got about 14 sometimes 15 if very softly driven on the freeway. IIRC my dads '68 Fury III 318 got around 15 maybe 16.
It is really too bad that regulations have driven so many radiator shops out of business. Aftermarket versions are available, but for me took lots of web looking.
