Realistic power from a "mild" build please advise

So my 68 f350 is getting a new to me 390. I plan on later swapping to a cummins diesel since this trucks only purpose in life is to pull my rockcrawler.

I should say I planned on puttin in a cummins. After spending some time on this forum I see that a fe can make some good power.

So, what kind of realistic power can one get from a 390 in the way of serious torque and reliability. I say mild as I would like to reuse my c8ae-h heads and I have to keep the compression numbers down for towing. Also what kind of fuel mileage, please don't laugh to hard.

The diesel swap will cost about 5500 once I find an engine and have it rebuilt. So I would have about that much to spend on the 390

Thanks again for all the help and advice.
