I'm impressed you could have the lower intake ported and install some 3:73's and some drag radials not to mention the pullies. You would easily break into the 13's.
I ran a 89 gt with well over 230,000 miles on it when the speedometer quite two years earlier and I ran a 9.54 in the 1/8th. I know your convertible weighs way more and your already faster than that.
I have an explorer intake sitting at home... but i figured y waste the price of gaskets... when i can just slap it on the other engine...
