Jerry, thanks for the info, I'm not that concerned about keeping it original. I'm not going to spend ridiculous $ just to keep it that way either but I may consider putting a decent running 235 back in it if I find one or take a second look at what would be involved putting this 283 in place of the six. It will probably need some freshening up also if I were to use it. My updraft carburator looks ok but there is some rust damage to the intake where the 4 bolts hold it together so that will need some repairs if that's possible. Lots of work to the whole project but I'm in no hurry.
