How much horsepower for 318?

I think that you will be hard pressed to, as the 73 Cuda that I had only ran 15.80's and this was with a 340 and a similar setup. But times have changed and things have gotten better by far, so it may be possiable. the only way that I see it is to have a good converter and more gear something like a 3.91 or 4.10.
