69 alternator usage
Can anyone shed some light on H/D cooling and alternator usage. My build sheet for a 256 gear, 442 shows AN 853, all fine and good! Now a 69 H/O w/HD cooling still uses the 853-37A? but a w31 w/HD cooling uses 1100777-55A?
The ***'y manual shows the w31 using the AG 767, 37a?
I've never seen definitive information on the H/O usage.

The 852/853 series alternators have an internal voltage regulator and I believe they are unique to the 442, W30 and H/O series. The 767/777 series alternators use an external voltage regulator (mounted on the firewall) and were used on F85/Cutlass and I suspect even the larger model cars. I thought the 55 amp alternator was used on cars with either A/C or heavy duty cooling whereas the 37 amp alternator was used on all others.

I was trying to unpack the lack of information on the HD cooling aspects. I understand the application for int/ext regulators. If a H/O w/HD cooling calls for 37A(no ac) but a w31 calls for 55A 777 but according to the ***'y manual it shows the 767, 37A. I haven't seen anything on determining HD cooling, so shouldn't the w31 use the 37A? as the H/O uses the 37A? I have seen documents showing the 442 with H/D radiator (3 row 400269 wp) 853.
