had this for years ,actually i had 2 but someone with one of those long ram(413?) stole it.i got them with a 2x4 weiand 383 manifold.the only numbers are shown and notice between the idle screws the big screw-air bleed ?and it has a smaller air cleaner flange than later types.
any ideas what its from?
is it super rare and worth thousands ?
can i retire ?
