Rebuilt 327 250 hp wcfb. Top number 6-1672, body 0-1465. These are good carbs to use on any small block Chevy 265,283, 327, 350. Great for low and mid range driving. Bought this a Hershey for my 283. Never used it. Why spend 2-400 bucks for a dirty used core with missing parts. These were used on 64 and 65 corvettes. 275.00 shipping included. US only. Anyone have a c1 hardtop for sale near Dover pa? Don 717-517-0204
