There is a 263 or 264 ci six thats a big brother to the 223 and wondering if there is any way to identify one without measuring the bore,I am thinking about trying to find one to put in my 37 Chevy p/u. I never had a good Chevy motor including the 235 thats in it and want to put a Ford motor in it and since those sixes have the carb on the same side as the 235 I think I might be able to make one look like a GM motor,there is a 61-4 big truck in a local junkyard that has a six and going to look it over the next time its there and I think I might be able to get to almost bolt in the 37 frame.

Butchering up everything I can get my hands on in Dayton Ohio
