Wow thanks for all the info!
Its a Delray 2 door sedan, I think it was the second cheapest model in '58 and the utility sedan or Brookwood were the only lower models. I like the look of the car without all the extra chrome, makes it look more sleek.
I do have another speedo cable and one of the plastic gears, maybe swapping that out would fix the speedometer.
The steering box leaks like crazy and is filled with very heavy grease at the moment. Since I already have a rebuilt one I was going to swap them out (eventually) and then send in the worn one for a $100 refund. For now I'll see if I can tighten it up and readjust it.
I found out at a place here in Wichita that the intake is indeed a 216 model, I was just gonna put it up for sale and get the Fenton dual intake and replace the Langdon heater plate with Fenton's model since it hooks right into the headers. I will probably stick with the 235 carbs, I already have 2 total and wouldn't want to deal with the hassle of finding another matched pair.
Getting rid of the oil bypass filter sounds fine to me. I've also been thinking about setting up a positive crankcase ventilation system, I've seen some guides that make it look easy. Does it really help keep the oil cleaner?
