I'm getting close to ordering a Superformance and am trying to figure out what engine to use. Like most folks I would love a 427 SO or a 428, but also like most folks I'm not sure if that is in the budget. If I go with a small block to cut down on initial cost, how difficult would it be to convert to an FE down the road? Do the cars have significant physical differences, or is it as simple as changing the motor mounts and headers?
