Hi, my name is Chuck from Florence AZ. I had a Demon 340 when I was a kid and used to bracket / street race it. Now that I am older and very marginally wiser I am doing a fun build!
I sold my Trans am's and found this beauty. I couldn't not buy it! I hope this helps some one else on questions and gives ideas of mods to other people.
OK enough chit chat.
This is how I got her. 52k orig miles slant 6 three on the tree.

OK I figured the easiest way to get the V8 was a whole car. Piecing it out would be expensive and a time consuming aggravating search (you couldn't give these things away when I was young now everyone wants a zillion dollars for parts). Low and behold 15 mins from me!

It ran and drove like a dream before this picture LOL. Just what I needed! 74 318 SE dart! rebuilt 318 a bunch of new stuff on it, power disc brakes, AC ( hey I live in AZ) , 8.25 rear. Cheap to!
Motor and trans out. K frame with brakes and control arms out. Rear out. Brake booster with lines and proportion valve out. In that order so far.
I ordered almost all parts from summit and a few things from ebay.

Ahhh the first of 4 or 5 orders from summit!
My list from summit was:
  1. Summit headers
  2. summit 2.5 inch full exhaust
  3. B&M Starshifter
  4. 6 pack hood scoop
  5. Summit chrome valve covers
  6. Summit chrome tri gauge set, white face.
  7. Urethane, Trans mount, Motor mounts,Lower control arm, Strut rod, sway bar, Rear leaf, Basically the whole car bushing kit from them. I used stock bushings for the upper arms. I think Urethane tends to be squeaky on those.
  8. Grant replica tough wheel with adapter.
  9. Brake hoses
  10. Carpet kit
  11. Tune up parts (just because I wanted them all new)
  12. KYB gas adjust front shocks.
  13. Trans Go TF 2 Shift kit.
From Ebay. Racing bucket seats a silver face autometer monster tach.

I picked these vintage slots up for 125$ 6 inch front and 7 inch rear. Those new cragars wont fit any more with the swap. These will shine like a new penny when I am done with them!

Started cleaning and painting stuff!
20160726_145401_zps146njg6b.jpg

Motor cleaned painted with new valve covers. I am just leaving it alone as it ran really good. I just want to get the whole car done before I build the motor.

I left the 904 on it. The car is a 3 speed on the tree. It was just to much money to buy all the 4 speed stuff. Let me clarify that, there was one or two people on here (thanks guys) that offered me killer deals on a whole setup, but I felt my money would go further finishing the car out then just buying a trans.

OK time to get the "lead" weight out!

This for sale or trade BTW as you see it minus alternator. It runs like a champ.

I had to spruce up the compartment it was old and yucky. Pressure washed and spot blasted and ready for high solid builds primer and a coat of Chrysler white and euro clear!

Ahhhhh! thats better!!! All pretty and white! Like ma Mopar intended.
20160806_112701_zpskkthde0t.jpg

OK!! Time for parts! K frame first!
20160807_124432_zpsruvmqzbl.jpg

Suspension and brakes! woot! getting there!
20160809_192428_zpsd8bob0fj.jpg

Real progress! Motor is in. I used the Energy suspension motor mount bushings. They were to wide. They didn't want to slide down between the ears. I ended slicing almost a 1/4 inch off the thick side of the bushing on each side. Sanded on the belt sander and now thy fit like a glove. and the motor and trans mount bolted up perfectly.

Headers and a bunch of other things this weekend coming up! Stay tuned!
 
Mmmmmm...nothing like the big brown truck bringing Summit goodies. Its like Christmas and your birthday rolled into one.
Excellent progress...and great choice of cars to spend the effort on:D (my Demon is a 72 also)
Sounds like your having fun too!:thumbsup:
 
Hey, off to a good start!!

Rock Auto and Classic Industries will also be good sources for some of the parts you'll want/need. Evans Wiring handy for an engine harness, too.

Enjoy :)
 
Great work, can't wait to see how it all turns out, have similar plans for my 68 Barracuda /6, even have a similar donor car all ready to go! Good luck!

Awesome! It's been easy with the whole donor car. You starting it soon?
 
Ok update! Got the headers bolted on. I bought the Summit brand and they fit perfect. I was happily surprised! Power brakes are in. If you are doing this swap you'll need the whole thing from the master back. Even the shaft that hooked to the pedal was different, but bolted right up. I used the proportioning valve from the disc brake car. I did however create two problems by keeping the manual steering in the car. First the 72 pitman arm is different than 73 and up. I took the pitman arm off the power box but the splines are larger. So I had to order a manual 73 and up pitman arm from Summit. After getting the ac compressor on and new alt on I saw another problem. Hmmm what adjusts the fan belt. Oh that's right, the power steering pump that is no longer there. So a little research to see what ma mopar did. They actually made an idler pully fir that but I hear they are rather rare. So I figured I'd make my own. Using Dorman part 419-616 pully two 45°bends and a few plasma cuts later I got this and it works like a charm.

A trip to orileys to get the right belt and finished! I did some more little things. Spiced the electronic ign in, radiator etc...
Here it is alive and breathing!

Ok more coming later. I'll let you know how the Summit exhaust fits.
 
You picked the perfect car to start with. learned my lesson about buying old rusty crap on ebay that cost a bundle just because it was an 8 cylinder. I should have found an old solid body 6, Id be done by now. Looking forward to hear it after the superchargers are in!!!!!!
 
Awesome! It's been easy with the whole donor car. You starting it soon?
It's the end of winter here in Aus so waiting for some slightly warmer weather to get started. My donor is an Aus model A body so hopefully its easy but I expect the odd hiccup. My 68 is already right hand drive so everything should be pretty close I hope. I'll be tracking your progress for sure.
 
Ok update! Installed the B&M shifter. They have some flimsy bolts to Mount it with. I welded 1/4 inch bolts to the floor. Much better. A few washers under the driver's side to make sure it was level. Make sure if you do this you have the seat in that you want to use so the shifter is placed comfortably. The cable came close to the header using the loop routing on the directions. So i zip tied it towards the block and wrapped the header pipe in fiberglass wrap. The only other problem I had was that the kick down linkage touched the shift linkage. Solved by bending the shift tab slightly down and the kick down lever slightly up.

I also got the 8.25 rear in with all new urethane bushings. The drive shaft I got locally ended up it was the same as the one in the car. Lol. Oh well I shortened one to get the car mobile. I'll drop the other one of at the drive line shop. 85 for shorten and balance. Mine is good but I can't balance it at home and I do see a small amount of runout when it turns.
I got the Summit dual exhaust installed. It fit great to the summit headers. Although I had to take 3.5 inches out of the mid pipe and 2.5 inches off of both sides on the axle pipe side that fits in the rear of the muffler. Other than that it lines up perfect and sounds really good.

Ok. More to come!
 
Been doing the grind on the demon. Some sanding. Got one of the front new buckets mounted. This part is time consuming fixing dings and sanding. Uggggg.

Ok got the roof, Window channels, and trunk edges sand blasted. Should be in primer in about a week (I hope)!

The booth is going up! I just have a few little things to address. I missed 1 ding and doing some glaze on any little spot I see. I have a schedule but you know how that goes Lol. I took off today and Fri to try and get this thing painted by sun night.
It may not go like that but that's the plan Lol.
  • Thurs: get booth up and finish going over car
  • Fri: retape and get final coat of primer on. Wet sand with 600. Cut door jams in.
  • Sat: look car over. Paint base. Paint intercoat where stripes are going.
    • Sun: tape stripes out. Paint stripes then clear.

Well it figures it was windy and rainy for a whole day! It's sunny here 350 days a year except when I take 2 days of to paint Lol. I am a day behind. Here it is ruling into the both
20161106_121902_zpsjeowbjlg.jpg

Ok got the chrysler white base on! and the intercoat where the stripes are going. Just have to wait a day to tape them out.
20161106_184930_zpsjfei2fmi.jpg
 
Well I got the stripes on! Omg what a lot of work. They came out great though! All that's left is to clean the both one more time and clear it. My "retro drag tribute" paint is almost complete. I won't give it away until the decals are on. You'd need to be old like me to recognize it lol. I'll leave you with these for now.

I am really liking those stripes! Excited to see more pictures. Keep up the good work
 
Well, I have been trying to get things done. I got the clear coat on and it looks great! I used advantage euro clear 2 part it's the second time I have used this and I like it. I have mostly only painted with single stage but I could get used to this!

I had all my decals printed from brmoffroad. Com. They were a sponsor of my son when he raced motocross and all around very nice people. They have also printed custom trans am decals for me that were amazing. Well... while waiting fr the paint to cure I decided this would be a good time to get done of the inside done. I had ordered the front seats from eBay 200 bucks with free shipping! I'll take that deal. The carpet came from Summit. The rear seat cover was sewn by me! (I have a post on how I did this in the interior forum) it matched to the T and looks amazing. The headliner was the card board kind. I initially tried to cover it in vynil with red stitching but it was to heavy and didn't want to stick to the card board as well as I like do I scrapped it and bought headliner material from eBay. I used the same patterns I had cut out to make the vynil and instead of stitching it I just used weld foam glue from home depot and carefully butted the seams and it looks flawless. I Andover covers the rear sails and speaker tray in this also. I polished the door sills with a angle die grinder with a light scotch brite pad. Now it's getting nice and cozy in there!

20161120_172415_zpskcljmdbf.jpg

the rest of my decals came in from brm so I figured I would start on them! With an extra helpful eye from my daughter and a little measuring the car is starting to breath some life! I still have more to go on them but I'm close to done. I still have the hood and trunk to do but that shouldn't take too long one I get going on them. I wanted to do some fun stuff before I got into the hum drum of sanding again lol. I'll leave you with this for now. Maybe you can see or remember what car I'm doing! I saw this car as a kid, how nostalgic! Boy in getting old!
