I would pass. Do it with the right parts and you will sleep better. I am always in favor of the most cubes you can work into a combo at a reasonable cost, especially for a dual purpose combo. A bigger motor makes more torque down low, and takes less time to get through the first half of each gear, having more average HP down there. Add in the benefits of less required rpm on valvetrain, more stall from the same converter, the list favoring a big stroker is long. Just keep within the reasonable strength limits of the block you run.
