Hi all,

I haven't updated here in a long time as I just post to the sites on Facebook. Here is the completed, up and driving, racing, cruising @ 75MPH with the A/C blowing 38 6.1 ProTouring HemiDuster with a EFISource Goldbox, Passion 5-speed, 3.73s, 255/40 18x9s and 285/35 18x9.5s Viper GEN III Brembos on SRT 14.25 rotors with DrDiff 12.7 rear discs. It's been a long journey but it's now a lot of fun!

I plan on attending MoParty in September, drag racing and auto crossing.

Very nice! I've caught some of your build on FB but didn't think to look around here to see if you were on here as well.

Thanks for posting it here. Very cool car.

Where did you get the front brake kit? Pretty sure I found some info once but drawing a blank now.

Wow. I too stuffed a modern Hemi in a A body. I really like the Hemi badging on the hood I never even thought of that. Cool. Thanks for posting
 
Awesome work!

I’ve seen a few of your posts on FB, I pretty much do the opposite and post on here and not on FB.

I've been frustrated with FB and looking for information later. Really don't like the way it works for stuff like this. So I am with you there.
 
Spec's on the wheels? Make, diameter, width, offset?

:thumbsup:
Front:
Enkei PF01 18x9 35mm+ offset on custom modified hubs with Michelin Super Sport 255/40, 14.25" SRT Challenger rotors with GEN III Viper 4-piston Brembo's powered by a Hydroboost/Mopar master cylinder. It stopS very well!
Hellwig 55917 swaybar, stock boxed LCAs, SPC fully adjustable UCAs, 1.02" torsion bars, Bilstein shocks, Delrin bushings all from Peter Bergman

Rear:
Enkei PF01 18x9.5 45mm+ offset on a 66-67 B-Body 8 3/4" with offset hangers, Michelin Super Sport 285/35, 12.7" DrDiff rear disc kit, stock 340 springs de-arched 1" with Bilstein shocks

I think the big question with this conversion is the cost and the difficulty. It seems like there is body massaging and everything is special to the conversion, motor mounts, adapter plates for tranny, headers and the list goes on. Probably $5000 in special parts and add to that the price of the motor.

THIS is the most truthful, accurate, and profound short analysis of Phlakebooke I have ever read!!!

Perfect info. Thanks for posting that!

So the brake kit was a @BergmanAutoCraft special? Guessing it isn't something he offers anymore.

Good questions:

  • Cost is driven by personal preference of intended use. You can do a GEN III Hemi swap a lot cheaper by say finding a low mileage 5.7 behind a manual and grab the harness and computer, bolt it behind a 727 with a 3.23 gear and a 275/60-15 and have a nice reliable 13 second driver.
  • Body massaging, the front and rear fenders are rolled, the fronts are mandatory to fit the 255/40-18s. The only other body modification was the modern Challenger gas cap
  • Motor mounts and headers are TTi
  • The drivetrain was mocked up in 2014
  • My front suspension and brakes aren't cheap, but's what I wanted
  • The motor is a stock 6.1 with a Frank Racing SCUD camshaft, ported heads and a cable throttle body
  • Bottom line is it's JUST like any other build, this is my last build and I spent 2 years of weekends assembling this from a shell once all the body (By a dear friend who passed away in Conroe, TX) and paint (JJ'sin Moscow Mills, MO) were completed. I also had the motor assembled as I had a fairly local GEN III racer clean, bearing and ring the motor and it was a very reasonable deal.
  • I did everything else, fuel, brakes, wiring, exhaust. The only other work farmed out was headliner and front bucket seats.

Peter can help you with whatever you need. I kind of went over the top. Their are cheaper solutions that will work well if you don't plan on running a road course or feel the need to STOP at 150MPH. There are also Mustang Cobra brake options available. IF you want your car to go around corners and stop, talk with Peter about a plan that can fit your needs.

Yep. Bought my Borgeson PS gear from him and have plans to buy more in the future. Current setup is fine, just need more caster and maybe another step up on the TB's. He has what I need, just pausing until the funds are available.

Understand that. Running a 13" Cobra rotor and C5 calipers right now, and have built a setup to use the SRT 14.2" rotors and 4 piston Brembo calipers (but haven't run them yet). Brakes are just a fascination for me so I am always curious what others have done. That's why I asked,

I wish I had paid more attention to brake aspect on my build. I simply got a Wilwood kit and moved on. She stops but not nearly as easily as I would like. Brake system is on my blue tape list.

Looking forward to seeing the car at Moparty!
 
Weird looking Mopar.... :poke:

:rofl:

Looks nice either way, just ribbing you
I was the oddball of the family. Dad was strictly a chevy guy and my brother followed suit. I went the mopar route. Truck was a dad/sons project that I took over the upkeep of when dad passed away.

It's better than anything I drive. :)
 
Hey Brian,
Great to see your car here. I'm surprised I didn't see it sooner.

Congratulations on the outstanding build!!!
It's definitely an inspiration seeing it on the road and track! :thumbsup:


I love the Hemi stripe on your Duster so much, I considered trying to put the same one on the Barracuda.
We decided to stick to our original plan of 69 Barracuda side stripe in black with no call out.
Sleeper style. ;-)


I think 2024 will be the year we finally finish our build.
Or at least I'll finish what I'm going to do with it. It will be complete in every sense but there are some items on Dylan's wish list that he will have to do/fund himself. I'm always willing to help with labor but my I'm already way too far over budget to think about any other "Improvements"...

See you down the road my friend!
Maybe Route 66? :)
