lt1s10, your point about weight hanging out in the breeze is well taken and as you stated "to run a blower on the street takes a lot of compromise". Still, I wouldn't start a project like this without using an OEM-type system. I was looking through the Radiator Express site 'cause they have a dandy little application software program where you can find the core area of any radiator. Anyway, I see that the 65 Chevy truck has a 25 1/4" x 17 3/8" core for a total of 438 square inches of area. Playing around with their chart, I found a radiator in the '75 and '76 Cadillac fleetwoods that is 32 1/2 x 17 for a total of 552 square inches. That's 20% more area than the Chevy has now and the radiator is about the same height, so the height wouldn't be a problem although you'd have to cut out some of the core support because of the additional length or use a Cadillac core support. Use a stock Cadillac shroud and fan assembly from a boneyard. Autozone has this radiator in a copper/brass construction and it's a 3-core, part number 433451, $209.99. Someone may even make it in aluminum.

you're right about the cooling by it being a pickup, but the el camino was hard to cool anything other than stock. i put that same motor in a 1970 conv. with the same setup i had in the el camino without any problems. i think it'll work just fine in that pickup with the right fan and rad.. talking about a problem though,in the el camino i had a 4 row rad. up front, 3 elec. fans, a 4 row rad. in the bed with 2 elec. fans running and on a 90 degree day it still ran 230-235. it just took it longer to get there. on a 75 degree day it ran 210. i believe if i had taken the finder liners out of the el camino it would have ran cool. one thing you are 100 % on is the elec. fans. i have owned all of them, and they never improved on anything.i bought some stuff one time that replaced the water in the motor that wouldn't boil, and for a while i road around with the temp. stabilizing at 260 degrees. you could take the rad. cap off at 260(you used a 0 pressur cap) and there was no activity in the rad.,on a cool day it would run normal. it didnt seem to heart anything but i didnt like seeing the temp. that high.
