235/60/15 Mt Drag Radial

I Would like to hear from anyone who has used this tire in the above size. The 'cuda needs a whole lotta help in the traction department. Current rubber is a 245/60/14 Cooper Cobra. Just goes to smoke when loud pedal is squished. The 340 is producing in the area of 400-420 hp at the crank. Trans is 727,stalls at 2500 with 3.91 in the rear. I intend to relocate the leafs in a season or two, so for right now I need a small tire that will hook. I'm hoping this will be adequate for the 2-3 trips to the drags and the weekend street use planned for next summer. Thanks in advance.
