too many variables to say.....
Your combo driven right, tuned right and hooking at sea level has the potential of running in the 12's. (assuming it weighes around 3200 pounds) That would also include a GOOD converter as well.
As goes for horsepower....thats another can of worms....who cares....just run it. To many people claiming to have 600+ horsepower in there Musatangs and getting slapped by a realistic 350 horsepower Mustang with everthing else being equal.
Go fiquire.
Just go have fun with it, but really,...isn't it what it's all about any way???? (Having fun)
