Wow - only a 71 pound difference. I thought it would be significantly more than that. I guess for the expense, 71 pounds on a street car probably isn't worth it. Thanks for the great info. Does anyone know the difference in weight between a 351C with aluminum heads and a 460 with iron block and aluminum heads?
