Welcome to the forum and congrats on your car. enjoy it and look through the stickies here as there is a ton of info gathered over the years along with lots of helpful members.
as for which is faster.....The enlgines if they are both LT1's should be pretty much the same. Some 9c1s have the smaller L99 (4.3 vs 5.7) engine but all Impalas came with the 5.7.
Another factor in which car would be faster is gearing. I believe all SS's came with a 3.08 gear and some 9C1's would have a 3.23 or a 3.42 from the factory. If the engines are identical, I would think the car with a 3.42 would be faster.
'95 Caprice SS conversion - Bonny Buckets - 96 Column, Shifter and Console - 3.73 Gear and Herter tune - Z/28 Cluster - Blazer OH Console - Green/Pink bushings - Chromed Impala Wheels - Eibach Springs and Bilstein Shocks - Corvette Engine Dress - the list goes on and still more to do...it never ends.
