What is the best way to get power out of a slant six? I know some turbo and few supercharge them. How much power can you get from rebuilding the engine with more performance mods. I am possibly thinking of building up my slant six instead of going through with a Gen III Hemi because it might be cheaper and the Dart would be more light weight. Any ideas. Something for street use that could still have fun in if I ever wanted to go autocrossing or some sort of racing. How difficult would it be to learn how to rebuild it yourself? Thank you for the advice.

I was thinking about turbos. I think the whole blow-through carb thing looks funky though. But then again, horsepower over looks. I am just thinking about it.
It is most likely going to be less $$$ than buying a Gen III HEMI and a new 5(or 6)-speed. I think just the engine and trans without any wiring and stuff is going to at least cost me $10k, then I have everything else to worry about.  Would be a very cool Dart but would take forever just to get the money to build everything.

import a 265 Straight 6 from Australia....The Hemi 6...and blow away the competition with that little monster.
I have put $1500 into the head along on a 225...500cfm Edelbrock, Aluminum Offy 4bbl...Tri-Y headers....if I could do it all over again....I would try to stuff a 265 under the hood

I already asked OzHemi about it. The problem is the 265 is 3-4 inches too long so I would either have to move the firewall back or get a Ozzie Front clip (which is much longer). Not only that but the 6 pack carburetors interfere with the master cylinder location.

Where theres a will theres a way....You can always move the radiator support further forward, remove the mechanical fan, and run 2 pushers from the front. If you mill some 90º aluminum bodies you can probably set the 6-pack carbs in a vertical orientation or find some motorcycle carbs that will fit...It would take some research but it would come out fine I am sure. I had my six all dolled up and I was taking out small blocks with it. Daily driver. about 22mpg with attitude. My next upgrade for it was a Turbo setup but I moved and couldnt take three cars where I was going.

Yeah, I forgot about moving the radiator support forward, the only thing is that it may be too nose heavy then, and I really don't want to modify the engine bay too much just in case I want to do a Gen III HEMI swap later on in life. I just want a temporary drivetrain I can still enjoy taking to muscle car gatherings and cruise in as I go.
I actually do have an all stock 318 from a 70 or 71 Barracuda but the only thing is that it is going to need a rebuild. I was thinking about doing something with that later on in life. Maybe something different like having a Blower on it.
I like things that are unique and that most people due. It would be pretty cool to adapt a supercharger to the slant-six. Kind of like these guys:

The way gas is going....is adding a supercharger really gonna be wallet friendly...You are adding more air...when you add more air you need to add more fuel...The videos are definitely cool though...

It's not going to be a daily driver, just a cruiser and something I can take to the car gatherings. Idk, I am just circulating through some ideas.

I'm gonna put this on my /6 Dart sport. Yes I know blow thru is better but I am doing it with ZERO budget.

Find a junkyard magnum 360. Have the heads cleaned and checked out. New valve springs, have the stock roller cam reground. Edelbrock intake for magnum heads, headers, and a backyard hone'n're-ring with cast piston rings, new timing chain/gear set and a hv oil pump with a bigger pan/pickup. Will make good power and you won't have to reinvent the wheel. You would be going with a well documented, proven performance combo. In the end would be much easier than doing any serious mods to your slant IMO because of the serious lack of custom engineering/fabrication required.
Approximately how much would this cost???

Old school hot rod approach always works.Have someone (who knows slant 6's)port the head,better compression,solid cam,4bbl intake and a header.It would be fun to see what you can get out of it. If it is a stick all the better. Can you stroke a slant 6?

A 225 is almost as heavy as a SB and about the same as a gen III hemi so handling is not gonna be much different. Bone stock even a 5.7 hemi is gonna make 3 or 4 times the power of a slant.
As for makeing a stroker slant, how much more are you thinking you will gain? It comes with a 3.4 bore and 4.125 stroke, very high stoke to bore ratio and with small bores and valves you are likely to only gain a few pounds of TQ and no HP, the same could be acomplished easier by switching rear end ratios.
