Don't forget Big Jim, the SVT has a more aggressive spark curve to go along with the compression bump. I'd be interested in seeing a dyno with your car on 87 and on 91. Not that I'm sending you the money to get that done. :p 
Based on what I know about your automotive knowledge, I trust that you know what you are doing. I can't say I'd recommend it to anyone though.For what it is worth, the SOP dyno can tell no difference. I know that isn't very scientific but it is useful. My SOP dyno could tell that there was a drop in low end power with the secondaries held open.
