And to answer your question, no, 245 isn't enough for 330+ HP unless they're drag radials or stickier. 275 is good up to about 400HP, from there you really should be around 295 all the way to 450HP. Above the 450 mark is a good idea to go 315s. If you want real traction, you'll go 335s. Of course, at that point, you may need spacers or mini-tubs.

As for the front tires in straight line acceleration, you want the absolute SMALLEST tire possible. Heard the term "Slick and Skinny?" Thats for 2 reasons... A) Less weight, and B) Less rolling resistance.

But as I said before, this is the wrong car for straight line acceleration. You want an American muscle car for that. The correct suspension (you know, the kind that doesn't turn at all), a V8 or better with plenty of torque, and CRAPPY brakes because the crappier your brakes, the less resistance (Some racers replace their brakes with drum brakes because they don't make any contact with the hub until they're braking).
