74 Challenger with twins

[YellowThumper]

Challenger build remains on temporary hold due to another project.
Fortunately I am on the tail end of it's build. Fortunately I also already have it sold. 64 Falcon Sprint.
Some of its funds will benefit Challenger.
Already drifting towards what will be its next priority.
Also have these in process. Plan is to replace the 15" Rallyes with these. Original center caps fit well but will be making the trim rings special. Along with the Rallye triangle (ish) holes and raised surface features surrounding them.

Where to start....
Been a year and a half since last update. Sadly enough I had to go back and reread my own project to get caught up.
Falcon distraction project completed and has now been shipped up to Washington St.
Slowly have been drifting back into Challenger.
Ordered in a builder kit of SS exhaust tube.
Not ready for turbos yet so I will build it from rear forward. Existing mufflers and back half has rotted holes in it.
Need to stave off asphyxiating myself.
Same mantra of building and keeping it drivable for as long as possible.
  Purchased a new shifter to replace sloppy old one.
  Remade the cam sensor setup for a hall effect version. Should be able to pick up signal easier.
  Started up again on the custom machined wheels that will mimic the Rallyes.
Picture is alignment setup for wire EDM start holes.
Round holes will be wired to similar triangle (ish) Rallyes.
Drilled hole is for "C" shaped wire cut that will define the profile for the raised bump surrounding hole.
Hopefully the vision turns out proper. Initially they will be 17" x 7" then will widen 2 to be probably 9" wide.
  Have and will install rebuilt door hinges.

Finally on this again...

Nice to see you back on the Challenger. How will you make the raised bump around the holes?  Welding? Make a die?

Will wire a slot above the hole that mimics the transition line of the bump and face. Probably will have him wire out a buck with same profile. Will bend up the bump from the cut slot and then weld seam closed again. Hand working tje face to eliminate sharp edge.

That's current plan. Hope it works.
Will also have to make my own beauty rings.
This was my test piece getting familiar with the bead roller and tipping wheel. Will shrink/stretch the face once lip is bent.
This is just fun stuff for now. Already worked on the cam trigger piece today as well.

This is some of the plan for the rim conversion.
@Brads70 In first pic the slot partially surrounding the holes is simply a wire slot. Face will be bent upward and then rewelded together from back side. Then raised edge will be handwork to the proper shape.
Center caps fit perfectly.
Went old school and manually measured a series of data points. Drew them up into a spline and printed to scale for test visual of surface. Once correct, I modeled the full diameter.

Wow seems like a big effort /lot of work.   
Maybe consider a couple spares while you have access to the equipment, wire edm etc... just in case you damage a rim ( pothole etc... down the road -pardon the pun , lol)  I miss having access to more equipment. But manage ok with the manual machines I have, just takes longer. 
What is the donor rim from? Are they plentiful and cheap ?  I ask as I'm sure you know the 17" aftermarket ralleys are available,  look good and are cheap enough? Just doing it for the challenge?

Rims are from all the big Chryslers with hubcaps.
Yes on knowing about the Yearones.
Yes x2 doing it because I enjoy this. Basically fill in fun (not a focus) in between the main build focus.
Will be making 6 of them. 4 to immediately mount, leaving 2 to eventually widen. Width to be determined by available tire size.
Already installed the hall effect sensor. Will be wiring it in soon. Reading up again on how to un-adjust the main board for this style sensor.

Was given free reign over the past couple years to finish the Falcon.
Now there is the necessary balance between house and Challenger.
Fixed gate latch - fixed sandblaster.
Worked on jacuzzi - worked on transmission.
Replumbed air compressor lines and added filters to eliminate water issues.
Started to blast the wheels in preparation for wire EDM work.
Purchased som A/C vents and promptly took one apart. Reviewing them for possible remanufacturing of the components. Will work on cost for tooling of the actual housings as well.
Committed to replacing exhaust so I got it up on stands.
Opened up the OD 833 to inspect inside. Everything looks clean. Even the synchro's look perfect. Willing to try it out.
Set up in mill now to drill shifter mount holes.
OD cover has pretty slick lever setup to switch the gearing around.
Not sure when I will install it. It is possible I will drop entire drivetrain soon.
Purchased a new bolt on style shifter to replace current one.
Unfortunately I have the earlier version...
Current one works but is very sloppy. What to do now...

[YellowThumper]

"Constrained" project creep in effect...
Exhaust still in process but have decided to finish more items since I am already under it.
Trans swap is on hold for now.
I removed the interior to allow welding in of frame connectors.
Also have decided to fully complete the turbo manifolds, hot side and wastegate plumbing.
Turbos to intercooler plumbing has been mocked up.
Next fireup will include the turbos. Even if they just blow air to nowhere.
Attempt is to push me into finalizing the EFI conversion.

Wow man, this is such a cool build! Can't wait to see it running.

I agree, hope he gets rid of the Ford soon so he will be able devote all his time to the Challenger.....

[RUNCHARGER]

It's hard to look past the cool fabrication but damn! That floor is like 1974 nice!

Thanks and thanks.
Falcon already resides up in Washington.
All focus is Challenger now.

"It's hard to look past the cool fabrication but damn! That floor is like 1974 nice!"

I consider myself extremely "lucky" compared to so many builds out there.
CA car and garaged most of its life. In front of passenger side rear wheel is a decent patch of rust that will take some surgery once the mechanicals are finally done.

[YellowThumper]

Passenger header is now 100% welded. As is the mount flange and tube.
Both the turbo flange and header flange warped. Had to mill both flat again.
Wastegate mounting in process.
Charge pipe is also moving forward. One pic has the green florist foam left tall enough to crush when hood is closed. This leaves imprint for where piping has to avoid.
My welding is ugly but functional.

[YellowThumper]

Wastegate layout for both banks have been decided.
Passenger side in process.
Moved on to further the ducting from intercoolers to tb.
They are ovaled/flattened so everything clears hood structure. Roughly 1/4" to spare.
Cut up finished plenum to allow relocating tje throttle body rearward. This move provided necessary clearance between pipe and header.
Nice to finally see some reality of what has been in my head for 10+ years now.
