I’ve done a little research and I’m leaning more towards the 454 as well. I’m aware of the fuel consumption (this isn’t my first big block). However, when you compare the RPMs each engine will be turning to produce comparable torque numbers, I have a hard time believing that a 383 is going to net any significant increase in mileage.

Not interested in diesel.
