Well, the GTO-specific setups are fetching $1000 in poor condition (big car stuff is slightly different than GTO, but it is getting expensive, too). In “correct” restored condition, they are getting $2500. I think it is rediculous. You can buy new carbs for around $800 & a new aluminum 1966 style intake for $500, & the rest of the gingerbread shit for about $200. That’s $1500 for new stuff, but it ain’t correct for a concours resto (I’m sure you know all about that with the COPOs & such). I’m glad mine came with my car (original tripower car, too). The chrysler & big block chevy stuff is even more expensive!
