Dont know how true it is but I was told that anything bigger than a four core is a waste because the air is already to hot to remove any heat past anymore than four cores. I would have to agree with the previous post. Of course finding a radiator to test that theory without shelling out some greenbacks might be an issue. Great looking truck by the way, good job on choosing a 460 over a BBC or SBC. Nothing against the other engines but I can appreciate the extra effert it took.

Ok, status for today (only 90 so far today)
1. external tranny cooler, finned tubular type, mounted to the frame under the passenger side door.
2. put back the prior fans, temp holds at 205 at idle
3. installed the #72 Holley jets.. idles much smoother
4. took her for a 10 mile drive.. temp holds at 200 or lower. around 50 mph the temp drops to around 180. at 60 its back around 195.
5. still running the 160 degree thermostat.
thinking about taking her to town, 6 miles each way.. show off to the guy building a BW 56, 502, TCI chassis.

Of course if you run into any problems, it will be about 3 miles away from home!

Curious: Have you checked temp on the tranny cooler.
No 2 on you last entry.you installed previous fans. On page one you had two fans and a shroud. In your gallery you had a single 16 inch fan with no shroud. What do you have now. Working great, what did it? thanks chuck

put the air cleaner back on.
Some else suggested the jet change, and I did to reconnect back to the dyno run.

I started out long time ago trying a single fan, couldn't fit it..
went to 2-12 curved blade fans and the shroud. (prior to paint)
these were the ones installed when I overheated in stop/go traffic 3 weeks ago.
I swapped in some straight blade fans(2-12in), thinking they would do a better job, but they didn't.. I woke up about 3am this morning and said, DUH, you changed the fans right before this latest heat creep problem.. SO, this morning I changed them back to the swept blade fans. and it seems to help more.
I think vents in the shroud might help more during driving, so I'll put that on my list of things to research how to do.
And, of course, I'm gonna talk to the local rad shop that built the radiator for me, and see what we can do.. for what I spent on it, it should work..

Sam,..WoW! ,What a difference..don't ya hate it when you wake-up at 3 in the morning with an idea ...LoL!
What's a Hot-Rod Truck you can't tinker with on the weekends anyhow???
Glad to hear your having fun! I'm wondering what the lower radiator hose temp is on some of the other Big-block engines on this forum and maybe around your local rod shows.??..How about it folks?
