Question obout intakes

I just bought a solid aluminum one on ebay for ~$50 (used). Single-barrel, but I plan it for a MPFI idea. Before that, I got an e-beam welded aluminum ones (trucks) cheap. Many say the later aren't good (porous welds), but sure is light. Some members here grabbed 4 bbl alum intakes off J.C. Whitney real cheap ($120) and I suspect some will be flipping them, but probably closer to the normal >$250 price.

Used Super Six 2 bbl intakes used to be real cheap, but people are snapping them up at the junkyards, so usually >$100 on ebay. Best is the rare aluminum version. Insure you get all the carb, throttle, and kickdown brackets, or it will be pretty useless.
