73 Challenger restomod

[dave73chally]

There was a tiny bit of surface rust I removed and sprayed with a rust converter just to play it safe. The undercoating was in really good shape and the car has barely any rust so I left it as is. Plan is to shoot the area with paint when I do the engine bay.

Welcome dave and good luck! I also have 73 challenger in the middle of full resto nor-cal also. I am in the middle of dash assembly wow!! what a job. Let me know
if I can help no expert but spent lots of time searching for parts and info. I will try and check more often then normal on this site. I spend most of my free
time working on the car. This car has lived up to its name a "True CHALLENGER".

Please post your numbers, my build is real similar to yours with a couple exceptions (496ci with .030 - I think). I would also love to hear it on the dyno and idle.
I'm going to guess 560hp just for giggles.

[dave73chally]

Will do. What did you do differently? Curious

[Denison636]

Just did the brace to mine to.

[usraptr]

Can't wait to hear the numbers! I'm guessing 605HP

Started cleaning up the wheel wells and sprayed them with undercoating:

[dave73chally]

Big weekend, got the engine bay prepped and sprayed. Used SEM eurojet trim black, layed down nice




Picked up my 512 and started bolting on some goodies, should be dropping it in soon!

[Mpdlawdog]

nice!  cant wait to hear it!

[dave73chally]

I went for it this weekend...was sick of the multi-colored green and didn't like the price quotes I was getting for a full paint job. Going for a solid driver and figured I'd give it a shot myself. Used SEM hot rod black single stage and SEM dtm primer. First time ever spraying anything with a gun, went pretty well. May have some tiger striping issues on the roof but we'll see how it levels out. I got 1 small run on the driver side drip rail but it'd dried decent and my t/a stripe will cover that up

Nice job, good to have it all one color.

[Mpdlawdog]

Looking good!  but now you are winning the race to get them done    I better get off my butt!!
