Re: 66 BBC Rad?
I use a Harrison, recored, with an mid 80 Z28 clutch ( hayden), 7( or 9?) 8 blade steel GM fan and shroud. 605 hp and it runs at where the therm lets it. OEM like, and very effective. No electric fans, no relays, no surpentine crap, no nothing but cooling.
So it can be done in a very oem way, and still cool gobs of power. Please forgive the upsidedown flip and non-oem overflow. I've yet to re-rig that.
OEM 66 rads typically had no shroud and a hand guard on the top of the rad. Now that oem look I wouldnt think could keep 600 ponies under temps. Plus both 66 and 67s used a fixed four blade fan, Unacceptable at 7400 rpms. Even with the new 467 limited to 6300 rpm, I dont prefer the "school bus fan" sound. So a caveat, true oem wont cool built engines well.
