8.75 Ratio opinions

I want to thank you for your comments here, as what you have, is what I am planning for my little beast. Needs an engine rebuild, so why not just go the 408, with low compression. My 360 is suppose to be 10.5 and I think that a 9.5 would be much more comfortable, and still have the torque that I want. And, I was unsure of the gear: 3:55 or 3.23. Granted, in high performance old Mopar, gas mileage isn’t brought up much, but let’s face it, it’s nice to have somewhat decent gas mileage. 3000 at 60 mph doesn’t cut it for that. Again, thank you for helping me decide.
