As for your last question, Pages 2 and 3 of my site contain spreadsheets for estimation of eighth and quarter mile performance. Go to the eighth spreadsheet and input everything for your car. Then, adjust the rear wheel horsepower until you get the speed correct. (Don't worry about the ET. It will be a bit off. The program simply can't take into account all the variables involved when it comes to ET.) Then, plug everything into the quarter mile spreadsheet. You might have to change axle ratio to prevent over-revving.
