For a heavier car like that, you would generally want to keep the torque curve a little broader and the horsepower curve shifted a little lower. But the answer to your question is yes, you can have a reliable FE and still hit the peaks whenever you want.

The FE market has really went nuts in the past 5-6 years and the aftermarket has lots of great parts available now.

Are you planning to use an existing 427 block, or will you be going aftermarket? Some of the older blocks will handicap you in your choice of camshafts.

Feel free to pick my brain. I'm a Ford engine builder and have FE experience.
