Any post about this topic needs to state the actual pulley ratio being used and the exact idle RPM.
This is such a big factor, any statement is worthless without it. twocents
200 rpm can make a big difference (7"/2" ratio 800-1000 engine RPM).

I am using the factory pulleys on the crank and water pump, and the standard pulley on the alt that was used on the toyota pickup.

74 Challenger, bought it new. In 1978 I replaced the original 318 with a 446 and 727. Mild cam, Jardine headers, and Holley Sniper EFI.
New engine! 511" RB, Edelbrock Performer RPM heads, Eagle rotating assy, Comp hyd roller cam, Doug's 2" headers.
