This is my '66 Chevy Custom big window stepside. It has a rebuilt 283 with and Edelbrock Air Gap intake and a 600 cfm carb backed by the original 3 on the tree transmission. It has dual exhaust with Flowmaster 40 series mufflers. It does have factory air conditioning as part of the Custom trim option, but not yet hooked back up. It also has been lowered 2in. in the front and 4in. in the rear. I have plans for it to be a 4/6 drop in the near future. I also have plans for it to be painted within the next few month or so, inferno red.
