Freddie, aren't your pulleys formed steel ? The pulley for the swp is cast. I'm surprised you don't have belts flying off the standard pulley's. Maybe I'm OK with that too. I will definitely change out the alternator pulley for the deep one, as that seems to be the source of that belt coming off.
I'm not way north of 400 hp, but it is a healthy 496, so probably 550 ? Seems the L88 and modified L72's should have been more than that, back in the day. Did they have issues with the cast pulley cracking ? I guess most of the that stuff came out more after the introduction of the lwp in 1969 and formed steel deep grove pulleys.
