Good morning all,
Starting a dedicated build thread for my current project- 1974 Plymouth Duster 440/727 build. This will never be a show car, or restoration. Its just going to be fun weekend car and make the occasional pass at the strip.

I picked up the car in Santa Rosa, CA from a nice older fella' named Stan. Took a little drive out to see it, and after crawling around it for an hour or so, made the deal and went back the following Saturday to pick up with a trailer.

As it sat: Totally rust free '74 that Stan used to run up at Sear Point until parking it in '81. Zero interior (all aluminum panels) no gauges outside of water temp and oil pressure with an oil pressure light. 6 Point cage that already had the front points cut out, and a single drag bucket. Car already has an A-Body 8-3/4 with 4.56 spool. Trans is a reverse manual 727, 3000 rpm stall with a Turbo action shifter. Battery is relocated to trunk with the bare minimum wiring and a single wire alternator. Driveshaft loop and adjustable pinion snubber are still in the car.
The car came with a whole file of receipts for the 440 including the machine work. .30 over, balanced and blueprinted. Flat tops (didn't say CR). I have the cam card, and ill verify but I believe it was 296 with .577 lift. Sounds massive. Car originally had an air gap that was stolen while parked so currently has Eddy intake and 750 carb. Schumacher mounts, headers and mini-starter.
Along with the car came tons of parts boxes, including most of the interior, a complete wiring harness (and then some) original gauge cluster.
Also found a few time-slips from '80 for 12.08 @ 109.

Since bringing it home: Ive got it primed one color, pulled the dash out, sourced most of those pieces and started repainting most of my interior panels. I've been working on the wiring harness, painted the engine bay and stripped all the trim off the car. Its surprisingly straight, and after blocking the primer, I probably will leave it be until paint.

Dang looks like you're already almost there! It will be a blast.

Thanks! The wiring is a little tough since he moved everything up on the firewall, but I do like clean fenders with the battery relocated, so I'm working with it. Got the harness all unwrapped, seeing what reaches, and wrapping it all back up as I go.
 
Also since purchasing it, I found another 8-3/4 third member with 3.55s and a sure grip ill be swapping in, (I wanted to drive it around town once or twice with the 4.56s) but my next big ticket item is building a custom cluster for it so I can get the dash back in and all wired up.
 
bet the 4.56 rocks!

Well... We only put a splash of gas in it to get it on and off the trailer and let it idle a bit to clear up any smoking (it had sat for a while), but there was enough left for one trip down the block and a pretty decent burnout with garage sale skinnies in the back...so they do indeed rock. :icon_fU:
 
Just a quick update for you all- since I had the heater box and dash out of the car anyway, I went ahead and replaced the heater core yesterday, broke everything down, treated any surface rust and painted the portion facing out with a flat black crinkle. Going to reassemble after work with my new stubby motor to clear the valve cover and Ill post pics tonight. Heater hose and nipples are on order.
 
A little note, if your going to run it much beyond stock rpm, a restrictor on the outlet from the water pump can keep your new heater core from damage. Keep up the good work.
 
I’ll definitely keep that in mind. I’m sure it will see a few high RPM runs. To clarify, is that going into or out of the heater core?
A few pictures. New motor was wired out the back so I used an existing firewall hole from who knows what and a fresh grommet to get it inside.

Scratch that- re-read your post- “outlet from the water pump”. I get ahead of myself some times...
 
Well, just wrapped up the plexiglass face for my new gauges... went to drill the wiper switch hole as the last thing and cracked it... so time to start over. Maybe I can center it up more this time.

No sir, the plan was to wrap it in 4d carbon and epoxy it into my spare bezel... now I’m waiting on more plexiglass.
 
Not to deviate from the gauge cluster too much. Since it’s a little stormy and we stayed in this weekend, got the trans cooler and new fuel lines run. The girlfriend (who does NOT like being under the car) even checked out the handiwork

Man, that looks incredible! Bet you could sell those! What do you have in it in time and materiels? Awesome skills.
