Took the Duster to the track tonight.

[ace26]

It did preaty good for running the BFG T/A radials,First pass i dogged it out of the hole and ran a 12.4 @ 111 second run i got it up on the converter and nailed it off the line,it spun thru first and most of second and got a 13.4 @ 105 so would ya think high 11's with a set of 9 or 10 inch slicks maybe?

The biggest,widest tires that will fit. Really,what's your goal? Go as big as you can afford and if you want to go bigger,wait,save and then do it.
4-links,or Ladder Bars will help you.

With a 9" slick you'll be getting close to 11's for sure. THere is a such thing as too wide a tire too. IT can actually slow oyu down a bit if they are too wide.

[Dennis Jokela]

I run 26/8.5 MT on my Scamp with a stock 904 converter and 3.91 gears. I run in the 11.80s.

The car hooks real well with about 15lbs of air.

Biggest fattest tires you can find? I got a set of 15X10 Shelby's (Ansen style) in the 5 on 4 pattern that are TOO wide for my lipped '65 Barracuda. They have 295/50R15's. Sounds just right for a Duster that has no lip over the rear tires.

What is your rear tire size at the time of the run?

[ace26]

Engine is 360 with 4" crank and bored 40 over 410 with eddy magnum heads unported ATM around 10.5 comp ratio comp cams solid 244int 252exh @50 520/540 lift eddy rpm airgap and an eddy 750 performer carb. Tires i have are right at 27" tall with 3.55 rear gear.

[Dennis Jokela]

Ace:

With a good pair of slicks and some gears,like 4.30s or so you should run in the low 11s or high 10s.

My combo is a 30 over 360 with a MP 508 cam,stock heads,Air Gap manifold, and a Edelbrock 625 or 750. With the 625 I have run a best of 11.97@113. With the 750, I have run 11.86 @115.
I just installed a Hughes 3500 converter, I have not been out to see what differance the converter made.

Have fun

Ace,what are you shifting at?And what are you going thru the traps at?

[ace26]

I shift it at 6k and i wasn't looking to hard but i'd say around 4500 to 5k at the end.This is just a street car for the most part,it's the first time i ever ran the car at the track just wanted to c what it would do,it's not set up for the track at all really as far as the suspension goes.

[425W5]

What was your 60ft times?

[ace26]

60' was 1.990 i had to baby it off the line to get any kind of traction.

Do you mind posting your tire size in XXX/XX/Rxx form. That's the only form I know.

I want to compare your tire size to mine. We have simular builds (minus solid lifters, wilder cam, and Magnum Eddy heads), as you know so I'm hoping to be within a second of your time.

[ace26]

Dust they are 255/60 r15's on 8 inch rims.about as wide as i can fit without a little massaging i could prolly get some 275/60 r15's to fit rolling the inside lip over on the outer fenders, would b close as hell to the springs and inside wheel tub.rims have 4.5 back spacing.I drove it to the track prolly a 55 or 60 mile round trip and made the passes,started with a full tank of gas when i got home still had a tad over half a tank left.

[dusterrcr]

Your 60fts are terrible. You can make this car work with good leaf springs good shocks and a pinion snubber for occasional strip duty.And will still handle well on the road.Good for low- mid 11,s Anything faster we need to start talking ladder bars and coilovers.Then it starts moving towards a race car.Go to a swap meet and get some old Weld or Centerline 8 or 10" wheels. Mount some slicks on them and take them to the track with you.I dont care how wide a street tire you put on.If you have good power and a good convereter its going to spin.

[ace26]

The rims i have on it are weld prostars 15x7's in the front a little wide for the strip i know but it is a street car with front and rear sway bars and 15x8's in the rear but i was thinking about getting some of those MT street slicks for the occasional 3 or 4 times to the track a year.

[dodger1]

ace, what's the car weigh? Thinking of a 4" for my 360 Mirada, which scales at 3600#.

[ace26]

It's at 3250 with me in it.
