Height vs. width for traction

I'm new to the site and have a question about drag radials. I just bought a 73 dart with a 440 has caltracks and 235/60/15 Mickey Tompson drag radials. the previous owner ran 12.6 as a best time but 60ft. times were in the 1.9 to 2 second range. I am curios if a taller tire like a 275/60/15 would hook better or if I should try and go wider.
