ran the Duster today.....

[318willrun]

'76 Duster, 2.45 gears, P235/60r15 tires, stock 904 and stock converter, stock exhaust manifolds with duals, stock low compression 360 long block (yes, stock heads) that I added a 4bbl (600 eddy/Action plus intake) and .427/.454 lift cam 204*@.050. (less than a stock 340 cam). I was impressed. It did better than I thought it would.

not bad at all!

Cool. What do you have for mufflers & @ what size?
Oh! And a 2.06 with the big tires and super 2.45 Hwy gear isn't to shabby.

 

[krazykuda]

Good run...

 

[Divenut]

Nice run man.

Yes and a highway car as well no OD needed. Nothing like hyundias passing u while buzzing like a chain saw at 60.
U have a good simple receipt for torque that's what can pull a 2.45 gear. Learned that lesson in the 70s w a 65 Olds
98 with a 425ci and highway gears that torque monster did not lose a lot of races ask my buddy w 71 LT1 vette w gears.

If you can find a shorter pair of tires, see how it reacts with an increased overall drive ratio.

Runs good.

 

[TF360]

Amazing with those gears- Car must be light

 

[RustyRatRod]

That's badass, man.

 

[vntned]

Holy chit man! That's way better than I expected. I thought those gears were really gonna keep you stuck in the 15s!!! Some 3.73s out back and you'll be well into the 13s!!!

Not the lightest A-body for sure. Bumpers are heavier and has the fold down rear seat. I did go to manual steering/brakes. I would guess it around 3300 lbs without driver..... never weighed it though

It's probably all traction and no slip? Nice pass!

our track is well prepped. no spinning. I was worried about hook'n up, but no issue.

i have used that cam in an otherwise stock 340 with 3.23 rear and 14 inch tires.It is the same lift as the stock 340 cam with a little less duration and acceleration was extremely strong.
Nice run!

No way this car weighs 2975. That must be a feather Duster with /6 and 7 1/4 rear.

• My '74 duster with the 318 is lighter and it weighed 3180 with 1/4 tank of gas (no driver). It does not have the "shock" bumper in the front like my '76. It has a 7 1/4 rear end. Smaller 14" rims/tires in back. No stabilizer bar. Drum brakes in the front. /6 torsion bars.

Naw, I'd be lucky if my '76 was 3300 by itself, but might be closer to 3400. I'll weigh it sometime and post it.

 

[Deucemopar]

Cool!!

 

[Dartnut]

That's pretty darn good for the gearing etc.
This combo really works!
Thanks for posting..........

Yeah, a little better than I expected. But ya know, if I drop .3 tenths, I'll run a 13.99 It'll return to the strip sometime, after I tweak another .3 by the "seat of the pants" out of town. My "seat" dyno is pretty accurate... LOL.................

1970-1976 Plymouth Duster

 

[Tooljunkie]

Thats great, looking forward to improved time.

Smart azz!! BTW nice run. Lotsa muscle cars back in the day would be eating your dust!

 

[furrystump]

I picked up two tenths switching from those mufflers to pypes race pro's. It also stopped droneing at 2500 rpms. Race pro's NOT the violators! Car isn't any louder either.
