Turbo and a 5 speed sounds like fun to me.
I get on turboforums quite a bit and can tell you that there is a lot of good running smallblocks cars and trucks on there.
My personal reason for going turbo on my duster was seeing all the power and streetablility of turbocharging. I have a custom turbo grind in my 440 that idles like stock and will be running a 3.55 gearset with an overdrive A518 in it. I am going to EFI next for total streetablility. There is a guy with a purple challenger with 500ci big block turbo that was cranking out 800+ wheel horsepower and was getting 18 mpg on the highway with efi and a 5 speed.

With a turbo you can also do what some of the TurboDiesel guys do, add an exhaust brake (2 with twins).
Then you can spool the turbo up while sitting and turn on the EB to build intake/exhaust pressure before launch, then release the EB as you leave the line with some RPMs up.
A bit harder on turbos, but I know it works.

Sorta' works like a variable Supercharger.

Assuming this is a street driven car that you can drive further than 1 block -

Turbo or 4" stroker - either will reward the $$ input vs the frustrations and street un-friendlyness of making a smaller cube NA motor run the #s...

Here's a buddy if mine's 318 Twin Turbo 318 with EFI and a MP .520 lift cam.

Heads are smogger 360s with $500 worth of port work LOL!!

Made 630 FWHP on the dyno. Comp is 7.8:1. Best qtr MPH is 132 mph / 3500lb car (you do the math)

3.5 gears - 727 - Street driven car, he takes it to the shops and to work..

Biggest problem? Traction. He runs 295/15s and can't make a 1-2 change at more than 1/2 throttle on the street without the rear end getting squirrely..
