The one on the right is a '65 and is a V8/4 speed car.
That has to be a rare car, more so since it's a convertible!
I had a '63 that I stuffed a '59 413 into. It was a total hack job, but it was fast enough to beat a '69 Z28, a GTO, and a 442 in a roll-on drag race on a road leading out of town that ended up with all four drivers getting cited for speeding by the CHP. Since I was in front, the cop saved me for last. The guy in the back got his ticket first, and came up to me and asked "What the heck do you have in this thing??" I was tempted to say "A BIIIG six", but I asked him what his ticket was for, and it was 65 in a 55 zone. I asked him how fast we were going, as my speedo didn't work, and he said when he was going 90 that I was pulling away from all of them. He left, and after awhile the next guy came up. "What do you have in this thing??" He had also gotten the same ticket.. The guy in the Z28 comes up, and once again asks what I have under the hood. I asked him how fast we were going before we lifted, and he told he didn't dare look down at the speedo. He got the same 65 in a 55 ticket... Finally, the cop came up to me, and said "Son, the way you flew past that graveyard back there, you're going to end up there soon", and gave me a ticket for going 65 in a 55 zone...
