Well, its all going to depend on the gears you pick and the tire height you go with....If its more street, go one way, if its more race, go the other....I know everyone likes to wind the pizz out of a Hemi, but they last longer if you keep it within reason.

I finally got tired of the 4:10 gears, even with a 31" tire and put in 3.73:1 gears....OMG, I should have done that 10 years ago...So now, to hit an rpm where the big single plane makes more HP is a very limited spot....My thought is, I would rather have the extra 30ft-lbs over the 11hp....and have it down low where I can abuse the tires more often.

We have 3.91 gear in our 69 Dart "street car" with a 29 drag radial, and its perfect for the track shifting at 5900-6k, but for the street, its a little much at 3k to hit cruising speed.

You have to decide what is your preference. The big single plane is nice. Distribution is excellent, and so is drivability, so, I guess try one and see...
