I just about have my rebuild complete on my 250 for a '66 Chevy pickup. It is the original motor, except on recommendation for a better carb, I have gone with a Carter YF that is rebuilt. I believe the application I found it under was a 1966 van, but it could have been on a number of vehicles. I'm not certain on the mounting of it though. It seems the float should go in the front, but I would really be unsure of the linkage if it was mounted that way.
Has anybody used this application and can you shoe me some pics?
