i ran 10.50's with my big block on SS springs and a snubber, with install issues on the relocation kit ( self induced ). after i fixed the issues and installed a set of sliders, I bet it would have gone even faster. the car hooked like it never had before. maybe some day I will put that pile of parts back together.

Starting with a 73 Duster and stock rear suspension, what would you run for bracket racing? This is not an all out tube frame car but a weekend warrior with a fairly warmed up 360 and auto trans.

What is the future plans for the car?It is easier and cheaper to build once.I've had my demon for my first car since 91 so been a work in progress.

Dam club thumbs.
It has ss springs,double adjustable vikings, rear sliders and a few claps on the front segments.It's had a best 1.37 60 last fall at 3065lb race weight. The double adjustable shocks made the car the most consistent.

I was at work today and didn't have time or the want to type the reply I wanted to on my phone, so here goes.

Your right, I didn't build the Dart, Dodge did. Same thing with the Strange S-60.

What I did do, rebuilt the front end, installed the Strange brakes on the front, Wilwood's on the back, installed all new brake lines, line lock and MC. I fabricated and installed the frame ties, same thing with the boxes for the inboard springs, the mini tub is also my work. The roll bar I installed, same with relocating the battery and all the wiring. Also the brackets that the kirkey seats are on are mine.

The engine block, sadly I didn't cast it, another project for Ma Mopar, Indy did the heads. Also I didn't do the rods, cam, pistons, cam and lifters. I don't have the equipment or the funds to do that kind of stuff. Same for the machine work. I did however take the measurements and have Diamond make the pistons, chose the lifters and who to have port the heads and intake. The cam I picked Brett Millers and Dwayne Porters brain and had Porter order it for me, Brett recommended the 1.7 T&D rockers, so something else I didn't do. I ported the oil pump and massaged the oil passages in the block, did all the measuring for clearances and gave the machine shop the numbers for the deck height I wanted. I also assembled the heads and set the valve springs to the correct heights, measured and ordered pushrods. Did a ton of clearance work on the block just to get the lifters in. I did assemble the engine, even degreed the cam in all by myself.

The transmission is Mopar, I did however rebuild it, removed the governor and made the spacer on my lathe to take it's place. It has red clutches, koleno steels, billet steel front drum, also I milled the slot in the stator support to help oiling, again not an original thought from me, John Cope gets credit for telling me. I also measured the drive shaft, yes I had it built, again I don't have the proper equipment. A man's got to know his limitations.

The engine was broke in and tuned on a dyno, again not mine. I paid someone else for the time and help and it was damn well worth it.

So your right I didn't build it, it's a collection of a lot of stuff other people built. I did however assemble it, chose most of the parts.

I work, save my money until I have enough to buy the parts I want to meet the goals I've set. If I had to pay someone to do all the work I'd have to play checkers instead. You post a pissy little, smart *** teen age girl remark, for what reason I don't know. What I do know is you can kiss this country boys lily white ***!

I was also a racer for many years at Bandimere. I would start with a good adjustable shock and a adjustable pinion snubber until you get it sorted and need to upgrade.

I love this reply SO MUCH!! This is the kind of crap that runs though my head all the time, LOL! I used to get really annoyed when people would see my car and say "where did you buy that?". Then I would try to explain that I built it from a $100 piece of crap (long story) to what it is today....when I was younger people would just look at me like I was full of crap...now that I'm getting older with mostly gray hair folks are starting to believe me....I guess I look more respectable or something:lol:.
 
If you are runnng leaf springs do you guys install a 1/2 leaf on the right side like we did 50 years ago?

What about using anti-squat in a leaf rear? Fromw what I remember from my leaf rear stock car stuff you need to control that body lift you get on the rear of carby lowering the front spring eye below the centerline of the axle.... just wondering.

when i ran super stock springs on my Duster iused the solid aluminum spring eye bushings. Other than that, ran them bone stock the way Ma Mopar suggested.
Tried clamps, snubber, yada, yada…
Worked best for me left alone.
Car was 1.34/1.36 60 foot everywhere at 3350 pounds running 9’s.
Not bragging, but i try and get my stuff repeatable, because i am a very competetive person and like win lights.
Over the years, my stuff has generally been better than the driver…lol
If i had thought i could get that car more consistent another way, i would have done it.
Remember one day running 10.01 5 times in a row with it. A body stuff inherently are good race cars. Doesnt take a genius to make them work well
 
The mopar chassis book recommends if using stock springs to clamp the front leaves. If you've done this, what did you use to clamp them? Did you make your own?
