1974 Duster
First pass- Garbage.
Car was like the 6th car down the track and it was cold. Spun the hell out of the slicks but HOLY SMOKES LOOK AT THE MPH.
14.38 ET-100.56 MPH-2.71 ST
The only difference between the car today and two weeks ago is the headers and the H-pipe is gone. Car picked up a solid 5 MPH.
Second pass- Slowest of the day disregarding the first wasted pass!
Car ripped off a mid 13 like it was nothing. Car was left in drive just like 2 weeks ago.
13.49 ET-100.19 MPH-1.93 ST
Third pass- Jetted the primaries one step richer, manually shifted 400 rpm higher.
13.31 ET-101.42 MPH-1.91 ST
Fourth pass- This was a lost pass that got my teeth on edge, best short time of the day! When I was shifting from second to third I missed and went into neutral! I instantly lifted, popped the shifter into third, waited for the trans to engage and mashed the gas again.
13.30 ET-100.09 MPH-1.86 ST
Fifth pass- I know I was running out of time (3:11PM) and the track was packed so I decided to go for broke and drop the exhaust. Dare I hope there was a 12 second pass lurking? The prior pass with a 1.86 ST should have been a 13.0-13.1. The track was a little slippery again and I could hear the slicks spin on the launch.
13.12 ET-104.14 MPH-1.95 ST
Sixth pass- I lowered the slick pressure in an attempt to get some more hook which is why I lost some MPH. Dropped from 12 PSI to 9 PSI. Best ET of the day (4:37 PM)
13.08 ET-103.4 MPH-1.88 ST
Seventh pass- Last of the day.
13.10 ET-103.5 MPH-1.88 ST
I could have made another pass but felt I didn't have anything left in my bag of tricks to get that last tenth. The car is over a full second quicker than its last outing. If I had a set of 4:10's out back the car would be flying in the 12's all day.
Took the car on the scales, 3675 lbs. which is where I calculated it should be with the addition of the 44RH overdrive trans and I'm sure the owner has gained 20+ pounds compared to 5 years ago when it was last on a scale with a 904. I do have an aluminum rear bumper reinforcement from a Feather Duster and might know where a front one is too. Both would shave a lot off the car.
Also the cam seems to make power right where Comp states it will, 5400 RPM. I do have a set of 1.7 roller rockers that might be able to extend that up a bit more.
Calculated HP is almost identical for ET/MPH 324/322
I'm very satisfied with the cars performance, it exceeded my expectations.
