AAAAHH!!,
I don't know about that? 358" SM/BLK 10.5 to 1, 1471 20% O.D. 30lbs boost, sounds to me like that should blow the crank out the bottom and the heads off the block, but it don't, and i know there's a couple other guys on here besides myself that run atleast that much boost with SM/BLKs sucessfully on alcohol.
