More then you would think (especially on street tires), Most stock BB converters are 12" on the belly, are you talking BB or SB??

I'm very sure you will be fine like i said, if your running street tires & not thrashing the dog poop out of it, I don't see it failing, Run a nice size tranny cooler too. 75 Duster, 451 10.87 @ 123.58 NA 97 Z28 6sp., 12.01 @ 115 on a 100 shot 71 Swinger. 360 magnum. 12.58 @ 105 78 cutlass, 469 BBC. 12.70 @ 108 on street tires. http://www.youtube.com/watch?v=Z2kqNmMfheU

So they should be able to handle more then that by just abit. That type super charger only increases torque about 100 lbs. or so. Added to the stock 383,s torque you should be fine imo. The stock verts arent built with anti balloon plates so Im sure they have there limits. Ive never heard of any stock vert failures over the years, but, most dont use them in high HP combos. Ive seen one post though by a member that the stock verts look like junk on the inside. I myself have never seen the inside of one.
