Looking for a bolt in all aluminum radiator

The Griffin F body is supposed to fit. Hopefully the Champion 4 core is quite a bit better than the 3 core.
 
I got the 4 row Champion this morning. I looks nice, and it is pretty massive width wise. Looking like Sunday or Monday I'll try to get it in the car.

Let us know what it takes to get it in. I'm really interested to see how it fits.

A little behind, but the rad is in, and it fit pretty good with little work. I pulled the old rad, the new 4 row dropped right into the lower rubber mounts. The passenger upper fit perfect, for the drivers upper, I removed the stock one, took a piece of rubber hose and cut it up to fit snug over the tank end, then bolted it down. Stock lower hose on it, used the dayco 70936 hose 565bbchevy mentioned. It went together as it was supposed to.

The fans are stock 4th gen f body pieces, and they fit like they're supposed to. They have tabs that slip over the lower rad support lip, up top I just made 2 pieces of angle iron for brackets to the stock shroud location.

I'm looking forward for your update on its cooling ability on one of these ninety degree days. We all know that the 403's will take advantage of the extra cooling capacity.
 
Today was a 90* day, I fired it up and broke in the cam at 2k rpm for 20 mins with a big blower fan in front of the car and the 4th gen fans plus a 16" pusher fan I have mounted to the condenser running, it never went over 180-190. Driving it around today at those temps it stayed in the 170-180 range with a 160 t-stat.

Great to hear. It's always nerve racking but very very exciting when you're breaking in a new engine, especially if you hand built it.
 
Yes, I rebuilt this one completely from a bare block, and it was nerve racking until about 5-10 mins into the cam break in, by then it had fired right up, went right to 2k rpm, and stabilized the temp. At that point the nerves gave way to more excitement.
 
On my 403 w/BBO heads, I have a stock aluminium f-body rad without the trans hookup, and an oldschool Flexlite aluminium fan. I've had the car out twice around town, and to work...stays cool. We'll see what happens when I start playing!

I like the f-body fan setup. If I can't find that in a local yard, I'm sure to find one out of an older Chrysler Intrepid.
