'72 'Cuda - 440 stroker twin t-4

[Cudas8me]

Hello everybody. I'm new here but just found this site so please forgive me. I have a '72 Barracuda (low option, but console slap stick auto) that is getting a 440 Source stroked (512) Brodix B1-BS headed, twin T-4 Turbo'd 440, so I think I belong here. I own a fab shop in North Vancouver, Canada and we work in construction but this is my hobby/passion. I tried to post pics, but have to lower the res first. I also have an 01 Durango R/T, 99 Cummins/03 Cummins/04.5 Cummins/06 Cummins in my shop (turbo's everywhere). If anyone follows Cummins stuff, my Uncle own Colt Cams up here and is helping many go fast on 6 cylinder diesel tanks. I just want to introduce myself so that I can draw on the collective when I get my Cuda together and need to attempt to tune it. First twin big block for me so I will definitely need help. Thanks in advance.

Welcome to the forum!

Pics?

Summit Racing has a couple fuel injection kits that support forced induction, including a few that can "learn" on their own and don't need a whole lot of tuning. One of those kits might be a good idea.

Let me know if you want me to get part numbers. I'll dig out an old catalog.

Cool, another Vancouverite,

I know your uncle very well, good guy.

Hope to see you around,

Thanks everyone for the welcome. I've figured out how to re-size in Picasa (quite simple really, lol) I've attached a few PDF's of it in front of my shop. Currently it has the tired out original small block it came with (Barracuda, not 'Cuda) that I built at 16. In my shop I have two 440's, a .030 over '75 (cast crank) and a std bore '72 (steel crank). For now the plans are to put the steel crank in the 030 over with the factory '75 heads(motor was on propane and mint), put as many aluminum parts on it as I can buy and make, cam it big and chuck it in. Once there I can use it for some N/A fun while I build the stroker out of the never bored '72. Already have the Brodix heads (new), T-4's, and wastegates along with many other parts for the swap. Car is auto and will stay that way(got great trans guy who does my diesels). Have to do it this way because with the small block in, I cant figure out the plumbing(exhaust headers for clearance etc.)

Welcome, nice stable list Are you building this as a drag car, or Pro Tourer?

[Cudas8me]

Sorry, forgot to answer a few. Am running an MSD digital 6 right now as it has two step retard etc, so am trying to plan out some of it. There are injection kits for 440's now but I'll likely be building a sheet aluminum intake for the big motor as I've built them for people before and I'd like to keep it all under the hood sleeper like. I'm thinking that's where I'll need to ask many questions. Throttle body size, injector size/style etc once I calculate the airflow requirements and all. Will be ordering the 512cube kit and will be getting my Uncle to give me a nice mellow idling cam, at that cubic inch size you can run a pretty big stick and they still idle nice, planning on driving the crap out of it everywhere. Car already has massive custom 4 core rad and Viper crate motor electric fan so cooling should be fine, rad was built for 1000+hp.

[Cudas8me]

To force fed, I'm building it simply as fun for me. I have buddies that drag, and will go play with them once in a while, but I'm planning on driving it all over in city traffic etc, so handling will be a factor as well. Going for the whole package I guess, just one step at a time as money and time allow. Owning and working at a fab/welding, shop helps a lot.

Cool, check out ProTouringMopar.com also, lotta similar build there. I have a '67 Coronet 500 that is probably gonna get a boosted 440 also, unless I can score a '68 Charger body.

OK, new to forums, please forgive. Not sure if this is how to post a new thread or not as related to my project. Regardless, here's the update. Had the car out in old-built-when-16-and-beat-on-extremely-low-budget-small-block-format, and something (too grossed out to find out what) is leaking VERY badly, left trail into garage; likely transmission output or main(always leaked a little). However, while out guy in crowd around the car while parked at Safeway tried to trade me his Mercedes for my Barracuda, felt pretty good except not a fan of WW2 technology, so said no. Felt better about hemorrhage from drivetrain. Anyhow . . . how does the collective feel about Mass-Flo EFI for my 512?? My new engine will be running about 9.5/1 with Brodix B1/B2 heads, an MSD 6al, and a mild cam to idle . . . looking for about 800 flywheel?? Any Ideas?

#1) 800 hp can be had with B1 heads in N/A form. Doing it with turbos is the easy way out

#2) The stock 440 block is fairly stout... but at levels over 650hp, the mains will become the weak point. No real mass under the main saddle areas in the block, and they eventually can crack all the way up the bore. There are ways to help with this with better caps, and/or girdle, etc...

[Cudas8me]

I'm well aware of all the ups and downs of the bottom end, if I was concerned I'd pick up a 400 or aftermarket block. Girdle will be used, thanks for the warning though, many don't realize the limitation. I realize B1's hit 800 just fine in N/A form and that's fine, but try the idle/overheat/smell/obviousness of it all and that's why the turbo choice. Mild cam, no idle overheating issues, easier on the drivetrain and on the bottom end as the boost makes the power progressively, that's why no supercharger. Looking for a super fun cruise machine. Turbos are the easy way no doubt . . . but in the age of technology why not. You can't turn the boost up on a N/A, gotta change a cam for more hp, how sad.

[Directconnection]

Hey... not dissin' on ya, bud!

I just read that you have some great heads, and some other supporting mods... just thought you'd be leaving some on the table with a stock 440 block

I have a '67 Barracuda that I ideally wanted to do a 426 hemi into it to clone the '68 hemi SS cars... but you know the price on anything 426, 472, 528.... So, a nice 550-600hp NA 440 will have to do. But... my dream would also be to do a turboed 440 someday.

[Cudas8me]

Whoops, haven't been on in a bit. For Direct, I certainly meant no disrespect, or to be pissy. Aftermarket blocks I'm sure will come later, simply can't afford/justify one before the R+D with this thing happens. Once I figure out how to work it all, then I'll probably have to pop for one. I'd much rather explode a $1000 short block on an oops than a $5000 one. Ahhh if only we all had LARGE bankrolls the fun we could have. I appreciate all the input. Love to see pics of '67 if you got any, one of my fav's and would be the dedicated/trailered drag car of choice if I can ever build one.
