I don't think I would go over 8lbs with 95 octane I would invest in a water /alky injection if I were running on the street. theres a couple guys on here that run blown on the street maybe they will chime in. My experience is on the strip with alky. how much boost do you need for the street? what do you have timing set at? what head gaskets? watched the vid I have always liked that body style truck

X2 what Bantam said, if you can't swing a water/meth injection system, at least go for a BTM to pull timing at max boost. Detonation eats the good parts too. Depending on your gearing, tire size, etc., you can still detonate at 8 #'s, especially at 8.44 static c.r., that's pushing the high side for a blower motor.
