Engine swap for a dependable k20 driver

I just finished a restoration on my 1970 k20 4wd. Truck is rebuilt top to bottom, I think I have touched every part on the truck. We changed the drivetrain to a .30 over, 454cid, 10:1,large grumpy Jenkins heads, and a th400. Now that the truck is together, it's clear that it's not going to be a mud racing truck as we initially intended. We mostly take a cruise on Sunday, but would like it be dependable enough to take off in it, maybe even a power tour. Let me know your thoughts on these different swaps or your ideas.

My 454, smaller heads, less aggressive street roller cam
I'm worried about the dependability of this motor.

5.3 swap
I love this motor but it lacks the bling factor

8.1 swap
It doesn't seem to be very popular, and I don't know what kind of mileage I would be getting into

5.9 cummins swap
I love cummins, the dependability, and the fuel mileage. I don't know if I'm excited about listening to that diesel knocking in my 70.

Any other ideas on crate engines?
