13.3's to 11.8's to Forget it...

I think the nitrous idea is a better idea. Big cam, high stall converter, 3.91’s when racing=fun. Put the 3.23’s back in while not racing=crap street car.
Smaller cam, streetable converter, 3.91’s for racing/3.23 for street use, nitrous for et.

You might be able to dip into the 11’s but nothing will get you there quicker than the sauce. (Nobody has to know you have it :usflag:)
