The new LS460 is rated at 380 bhp. The older GS400 was rated at 300 bhp. I wonder if we resleeve and stock the good old GS400 to GS460 (4.6L). Would the older GS400 have similar hp as the new UR 4.6L motor. The reason I post this question because the GS heads are pretty for stock and with increase bore and stroke would be competitive with the new motor.
