3.91 good or bad

Hate the 391's the motor just screams at you going down the
road.Been using 355's for ever and the best set up I ever had
is in my 71 Demon 355's with a 5 speed tranny.5th gear
around 1800 rpm on the highway and it will run at 75 80 MPH
all day without the need for earplugs,If anyone ever gets a
chance to drive an old MOPAR with a 5 speed do it you'll
love it
