What do you really want?
Do you want 330 ft-lbs from 2000-5000, with a 3.08:1, or do you want 300 ft-lbs from 2200-5500, with 3.42:1?
Both are going to deliver the same wheel torque, and same MPH at the upper RPM listed. So does it even matter?
HP is a calculation of torque x RPM / 5252.
Both of these examples make 314 HP.
The lower-revving one will last longer, get better gas mileage, and make cleaner emissions.
You can easily build a junkyard 350 to do either. Same cost either way. Mostly about cam choice.
The lower-revver may run cooler, but may need more octane. The higher-revver may sound better. Depends on individual preference.
When I was still a teen, I had difficulty working out how to make my '71 Camaro L65 spin the tires. I wanted it so I could move my right foot from holding the brakes to flooring the loud pedal and instantly have both rear tires doing about 40 MPH as the car was going 0-5 MPH.
The lower-revver above will do precisely that with a 2500-stall torque converter. That's all it takes. The higher-revver will do the same, but may want a 3000-stall. That costs more and requires investing in transmission fluid cooling.
So, which do you want?
I can't tell you. Anyone who can should be distrusted.
