What is a cast iron 2bbl intake worth

My thought is $200 for an alum 2 bbl, $100 for an iron 2 bbl, and $20 for an iron 1 bbl. Why fool w/ 2 bbl when a shop now sells an MPFI alum intake for $850 or will adapt an alum 4 bbl one you provide for $480. Add something like a Holley Commander 950 controller ($400 ebay) and a throttle body and you have a modern engine control, especially w/ an 8-pin HEI (950 can also control spark timing). A carburetor will always have severe limitations, w/ only possible advantage that your wife may never be able to drive your car (choke and all that).
