I agree with Bob. and even if you were going to stroke it and build a strong SB, I would still go with the 351. I had one stroked to 418 in the Cobra that I had and it put out over 500 horse and it has been running since 1996 with no problems of any kind. I ran it hard but the cousin I sold it to just drives it and shows it, so I guess it will last forever.
