mopar65,
Thanks for the compliment. It's no show car, has a few battle scars. lol
Sounds like you built a real nice engine. Mid 10 sec. pump gas street car on a little tire is very impressive! What rpm do you shift and trap at? What was the difference in trap rpm going from the 4.10 - 4.30 gears.
I have heard nothing but good about Dwayne Porter. I will talk to him about heads and a cam, for sure. I was planning on a set of ez's but I am really interested in Trick Flows new head.
There is a lot of weight that can come off a Duster, just depends on how far you want to take it. I could easily get another 200 off. Safety glass windshield, alternator, carpet, iron heads and water pump housing, funny car cage, heavy scoop, 3 lbs of rubber in the tubs. lol
What trans. are you using?
There's a lot of "ink" that you should go big, 500+ inches. While there are good points to that, (especially if you're starting with nothing) sometimes we lose sight of SIMPLE and CHEAP, right? One of the best bracket combos I ever had and would repeat run after run...it was DEADLY consistent and made over 300 runs before I sold the car. All it needed was a driver...LOL.
.030 over 440
OE crank
prepped LY rods (gasp!)
TRW replacement 440 4 bbl pistons (GASP!) w/hand made valve reliefs. Right at 11:1 as bolted together.
Crane R280 roller cam (WAY to big, but that's what I had on hand)
906 heads, 2.14/1.81 ported. Flowed mid 260's on Holton's bench
MP M1 single plane 4150 intake
Adaptor and 1050 Dominator (no changes other than jets)
OE Mopar elec distributor and MSD 7AL
2" Hooker headers run open, no muffs.
Alum drum, roller 727 (only footbraked)
8" Munsinger converter
8 3/4 with 4.86's and a spool
Ladder bar with 14x32 rubber
73 Cuda right at 3300 with me on board...
10.40's @ 127 almost everywhere we took it at sea level. Best of 10.38 @ 128 on a cool July morning at Somona. High 10.90's at Fallon one fall I drug it up there.
thanks for the info. i cant take credit for the short block becasue i bought it used off a guy from moparts. he built it for his street 66 B-body and then decided to build a 500 for his car. i only payed 2800 for it and thought it was a great deal at the time.now the roller cam and heads i bought brand new from porter racing heads. well between the short block and the heads i have about 6200 in it. i did install the heads etc. the trans is a TF727 built by me with cope racing transmission parts. sorry i don't really remember what the rpm threw the traps were its been to long, but if i remember at the time i was shifting at 6500 when i had the 4.10 gears and i think my friend was shifting at around 6200. well if i ever get my back fixed( i have 4 herniated disc in my lower back, started getting spine shots and have one left. the doc said if they don't fix it i will probably have to get back surgery.) I hope to start swapping parts over from the dart to the duster. it is a all steel 73 duster that i put the front-end from a 72 on it. it does have fiberglass fenders though. when i get the money i am going to get a fiberglass hood and bumpers for it etc. I was thinking about using lexan for the windows but not sure if i want to go threw all the trouble of keeping them clean etc. i dont have a shop so my car sits out side all the time.here is a few picks of the dart. thanks Bobby also threw a few pics of the duster its the red car.

I think going back to a 3sp, at the expeced weight of a B wedge with some alimunum will really mess with your suspension tuning and it will be slower even when you eventually get it to work. Your choice - but I'd leave the 'glide.
Here's a "for instance" on a B stroker:
383 + .030
full block machining but stock caps and main studs
pump gas (91 w/10% ethanol)
Stealths - Level 3 hand ported
Muscle Motors 4.25 stroker kit (4.25 x 4.280 bore is 496")
modified stock wet sump oiling w/stock pan & windage tray
port-matched RPM dual plane
custom Comp solid flat tappet, under .530 lift, under 244° @ .050, 1.5 rockers
belt driven water pump & p/s pump
Factory exhaust manifolds, 2.5" modified stock type full exhaust
Stock factory air cleaner (car won 1st in Stock Appearing at Carlise)
This is a low maintenance, pump gas engine, running street type carb, intake, and exhaust. It's made about 430hp to the tires, 450tq. Depending on your math that's around 510-520hp.
With .070 more bore, a real cam, race intake, and race headers I would imagine another 50-80hp is easy to get on the same fuel without exotic oiling, vacuum pump, or alcohol. It's barely touching it's potential as it was built as stock appearing and all street duty. The 383 is not my first choice for block - the 400 would be stronger.
dusterdoug very impressive car and times.:cheers::burnout::burnout:
Nice looking car! 4.86's and a 727, what did it 60ft. and what rpm did it trap at?
I agree with the loosing sight of simple and cheap. I'm starting from scratch by choice. I've got some stuff laying around, just not what I want to run. I think, lol.
Thanks again for all the replies, keep them coming!
No Chebby in my mopar ever, can't see starting with a inferior engine.
I know there are sooo many variables to consider when you're off a few on the big end, but I figure [usually gets me in trouble lol] that the best time to consider everything you can is when building. Agree on the no radical ramps, can anyone suggest someone to spec. a cam for me that understands the difference between a bracket engine and one built to make the most power possible.
I may be wrong but I think with the old engine going through the traps around 6,500 with very close to stock 452's the engine was past peak power and that could contribute to the inconsistencies in the last 320. I video taped my tach, around 5,100 at the hit, shift 56-59,000.
Thinking better heads and less gear to have engine making good power in the last 320?

Awesome looking car, love that body. What does it weigh?
It was a slug at 60'. With 2500 leave and a 5100 converter flash, it would only go low 1.40's. On the positive side, thats why it was so consistent, it always hooked. Anywhere.
Right at 7000 in the lights, about 7200 in really good air.
You mentioned the alternator in your list of removable weight items. Don't do that! Nothing better than 3 days of racing and never needing a battery charger! It's 5 lbs. costs no HP and it's one less distraction on race day.
