Have you ever raced a 351? I would hope you are doing at least high 12's with your car. Like I said earlier, the fastest time I have seen was a 12.85 from a 351. You might be surprised at what your car could do. 351's have been selling for $25K-28K (ebay/BJ) over the past month. Two years ago they were selling for $37K to $45K.
