Thank you guys. C5AE-C it is. Did some e-bay looking around and of course a little surprised at the $. I base the build date, best guess, on the glove box Owners Manual w/owner card and the date the car was picked up the the dealership May 29, 1965. Not on the door data plate June 1, 1965.
Jim; thanks for sharing the engine tag info on your car. If you have you original carb tag ? To carry this a step further ? A quote from The Marti Tag Book speaking of 65 carburetor tags pg.97 "the engineering change level, similar to the engine tag change level ". That engineering change level is the first letter of the bottom line on my tag ' C '. Same as yours Jim ? Thanks, Brian
