Yes I have a BAP... I think right around the high 6, low 700 mark would be fine...Mid 600s is the word for safe limits... You can crank it up to mid 700s but you'd definitely be risking it everytime you got on it. Do you have a BAP?
79 pulley and 93 octane.. the closest E85 is probably an hour away one way and that's just a guess..What pulley & fuel are you using? Oil pump gears should be your next mod... E85 if it's readily available would be safer then pump gas & add more HP.

I would be satisfied lolBased on what?
