SB 6 Pack on EBay

I bet it never gets used due to the cost of everything else that is required to do one correctly. Let's hope a FABO member bought it thou.

An inquiring mind would like to know what the costs are for a complete six pack/barrel set-up. The large hardware items are the intake manifold, carbs and air intake. Are the linkages hard to come by (throttle and kickdown if auto)? And is it expensive simply due to limited supply of original and even aftermarket parts?
