Champion radiator - I cut her open
Update:
So o was bored and impatient yesterday and wanted to put some of the suggestions to a test.
I went down to the car wreckers and found a early 2000's ford courier radiator. 26" wide and the hose locations were identical. Top and bottom tanks, but very thin. The hose width was a bit smaller but I managed to find other hoses that would work.
I put my 7 blade 18" fan on, but didn't have a shroud that would work.
Filled her up and bled the system, started her up and let her idle for a while. Filled her up some more and put the cap on. She didn't get above 190f the whole time it was sitting there idling, which was about 20 mins while I adjusted timing etc. I'd have to fabricate the correct mounts to match the rad, so I just used a bunch of zip ties. :)
Went for a cruise to get some fuel and then back home, temp all good.
Checked everything when I got home and all was still in place.
Went for another short drive in traffic near the beach and she still didnt overheat...
I couldn't believe this thin Lil radiator would cope, but it did. Thought, ok, let's try highway drive, so I drove to our workshop, about 15mins up the highway and temp sat at 176f the whole way and back.
So in summary, a 26" thin radiator, with a mechanical fan and no shroud cools my engine. I definitely need to make a shroud and Mount it correctly, but I think I'm well on the right track now.
Thank you so much everyone for all your help.
