As for tuning, I've seen just as many dead dog big blocks and Hemis as I have Slants. Just because you swap in a V-8 doesn't mean you can make it run.
Your statement begs the question- Looking at the original post, what makes you think the OP will be able to obtain the results he desires from a slant six?
I can make a turbo four that destroys most V8 but can point out hundreds if not thousands of people who can't set the cam timing right on a 2.2
Setting up a small V8 would be less complex than setting up for a forced inducted slant six that there are no "bolt in" kits for.
My 5.9 in the Duster with 44RH overdrive & lockup gets better MPG than a stock slant six with torqueflight, the OP is under the misconception that a V8 can't get good MPG.
I recall one board member seeing 29 MPG on a V8 Barracuda he was playing with.
I can understand if the OP wants to continue with the current setup because it is there, but forced induction more often than not is going to wipe out any fuel savings he might be getting by running a slant six.
I'd slap a header on it, better intake and small 4-bbl and call it good. Should be able to get a few more mpg out of it and a boost in power when the pedal is depressed.
Swapping to a lockup trans is a no brainer too and should be easy to find.

I am a slant 6 enthusiast, but honestly, you'd be better off following hotrodave's "super duper gas mileage 318" thread in the best of....
if you want to make things more fun, find an A/F body A833OD setup. my duster has an A833OD with a 3.21 rear, and it's peppy (it ain't fast) but it's fun to drive, and I consistantly get 24-26mpg in mixed driving. I bet with a mild magnum headed, hydraulic roller 318 with a t-quad, mileage would probably be as good or better mileage, but with 2 1/2 times the HP (my '76 duster was rated at 101 net HP)

Jeez... A guy has an idea to do something different, something pretty unique, and most of the advice offered is go with a 318
YAWN! 
As I pointed out, look at the posters first post- He has a misconception that just because he has a slant six he will continue to get "good gas mileage" with a supercharger installed. No offense but a slant six with a non-lockup isn't going to get the best fuel mileage numbers which seems to be a major consideration.
A belt driven supercharger will just make things worse, a turbo would be better if a touch more complex for the average novice.
More power and mpg would be had if a lockup trans (cheap upgrade) was installed along with a header and small four barrel.
If you want to turbocharge or supercharge a slant six, then do so but don't expect to get great mpg fuel numbers when the baseline of the vehicle isn't super great as it is. Minor upgrades will really pull the numbers up and still make the vehicle fun to drive.

I don't think you were around when I first built the TT440. I got more bashing and "can't do it" than you'd care to believe.
It took me a long time to iron things out but I did what I could with my very limited budget. Some of those anti's turned around and joined my side. Others still bash me.
I really don't care. I built it for me.
If he wants to boost a six, let him do it. It's his car.
I still say turbo is the way to go. 
IF i were to hop up a slanty, I'd go turbo, as you should be able to cobble together something pretty reasonably, without the parasitic drag of the belt driven supercharger. also, Port EFI is a must--unless you have a hyper pack intake, fuel distribution sucks on a carbed slanty, with the center two cyls running way rich, and the outers way lean due to the differences in runner length

Nobody in here is saying it can't be done. It can be done, and it has been done. Our point is, in terms of the OP's hp and mpg goals for the slant, for the amount of fab work and cost invested into it, when you boil it down to the basics he will have more time and money invested into rodding the slant than following a proven and well documented v8 swap. I think most of us have been there, done that at one point in time where we ended up doing something that turned out to be more time/money than it was worth. Just trying to save the OP this experience and point him on a realistic and relatively easy to follow path.
