63 dart v8 swap
Yeah, they're a good bit different. Remember, the 63 didn't have a V8 option and was actually built around the slant 6. 64 was the first year for the V8 and if you have them side by side, you can see a pretty drastic difference. I didn't know all that myself until I got my 63. But it really didn't matter to me, because I am sticking with the slant. The little cars are so light, it does not take much to make them move respectably.
