schumacher mounts and tti headers cost about the same for both. there are exhaust manifolds that work for both bb and sb, and cost about the same. there are no cheap *** headers that capture the steering for a bb like there are for a sb, but you can buy the cheap hedmans and try your luck and fit the to a low deck. they work for some people. used intakes cost the same for both. core engines can be had for about the same cost. core transmissions cost the same, and he already has one of each. machine work costs the same if you are going to build it. radiator cost the same. exhaust cost the same. they use the same starter, alternator, carb. you are going to need the same tires, and rear if you plan on going 12s. pistons probably cost more. thats about the only thing i can think of that might have a significant difference in price.
