'65 Cuda - 273 rebuild or swap?

You guys are all correct. It just depends what you what you want out of the car and whether the 273 can make it happen for you. If you are on a budget, a complete running 318 or 360 might fit the bill. You realize that with a bigger engine you may need a better transmission and a 8 3/4 rear end along with headers or at least different exhaust. Really your choice. Tmm
