I would not say that a 408 is too much for a street car. If you build the rest of the car accordingly, the extra power will just make driving more enjoyable. Its like rwhite65 said, "how fast do you really want to go?"

Parts are interchangable and costs are roughly the same as well. Cost, part availability, and interchangability are not going to be an issue with a 351. Finding parts for a 351 stroker motor as just as easy as finding parts for a 302 stroker motor.
