Going to try and get more involved here so thought I'd share my winter upgrade. Throwing a little turbo on the stock 225. It's a GT2871, blow through with the holley 350 two barrel. Not trying to make a bunch of power, just want to have a little extra torque. Going to try boost referencing the mechanical fuel pump, I've never done it but lots of people used to do it in the early days of blow through so we'll see.

Be sure to put heat shield around the exhaust turbine, they get hot. Extending over the manifold will help too.
 
What do you plan to use for carburation? Check out this YOU TUBE site. This guy is doing a turbo on his carbureted car.
 
Cool build. I’m a fan of boost and I’m following. Do you have any baseline data like Dyno or drag strip numbers to compare with?

Fuel, maybe a rising rate pressure regulator. Do they make a high output mechanical pump for the S6?

I seem to remember that, from my ownership of a non-stock Dodge Spirit R/T.

"They" don't, but anyone can; here's the recipe:

One Carter M2996 fuel pump. Original equipment on all 1960-'63 Slant-6 engines (part № 2084 859 or 2279 914); this is the bolt-together style of pump. It doesn't have to be new, but it has to be the original Carter pump; that is this one. If the pump does not look exactly like this what's in the pictures, it will not work.

One Carter M6903 fuel pump, a current-production high-volume item for Mopar big blocks. That's this one.

One new diaphragm-and-spring assembly with the dimensions appropriate for the M6903 pump, but with a four-to-five pound spring rather than the nine-to-ten pound spring originally found in the M6903 pump. This can be had by specific request from these people.

Disassemble both pumps—no need to remove the valves from the valve body, nor to separate the air dome from the valve body. Reassemble the M6903 pump using the custom diaphragm/spring assembly and the lever arm from the M2996 pump.

Voilà: a (very) high volume Slant-6 mechanical fuel pump.

Yes, your 100% correct and I loved the A body R/T cars. Great room, well equipped and lots of potential to exceed the stock 100 hp per liter.

Great tech tip on the slant six pump.

Those hats cause some really strange distribution problems. At least on 4bbl blow through stuff they do. Not sure what it’ll do on a 2 bbl
I’ve used it on a few combinations, from approximately 500 hp to about 750, worked great. I don’t expect any different here.

Did you do any extensive testing with either combo? I used one on a twin turbo 468BBC at 900 ish hp and had two cylinders we couldn’t bring the AFR down in. Switched to a CSU carb hat and the problems disappeared.

Only basic mph, plug readings and O2 in the Downpipe. Was going 136-139 mph at 3400 with a basic 440 edelbrock heads. Usually ran it pretty fat so might’ve covered up some issues, but never saw a plug that was alarming. I have heard some say that they start having issues above 800
