Ha ha...I just caught this thread. Mine made around 80-100 passes in 9.90 form last year, as well as lits of street driving.

Still learning, but something happened and it nipped the piston. Either the plug damage, too lean, or too much boost. I'll take the blame for the tuneup, but it wasn't the parts fault.

Just about back togetter with a new slug ready for BRACKET RACE season and terrorizing the neighborhood.

Mag'd the cast crank and checked it for straightness...good to go!

Last year I blew the 4.30s I had in my car and put 3.23s I had laying around and my 60ft was still the same 1.50 and the et was still the same, usually 6.9 to 7.2s. That's in an 72 dart with a 499 with a 3,200 stall. I did put shorter tires on 275/50 15 in place of the 295/65 15s. I was shocked to find out it ran exactly the same.

I agree as you have the power for 11.0's at 120 mph. Conveter and some chassis tuning and you could be in the very low 11's. Ron

I just found this thread, and it gives me hope! Thinking about taking my Duster to the track this year with 3.23 gears, 28" drag radial, and 9.5" converter.

Do any of you know your trap rpm?

Whittled down to an 11.1 @ 121 mph end of last season. Trying to resolve rear suspension issues.

yeah, I like this thread. Right now, the parts I have are pointing to me building a 451 low deck for my 67 coronet. Thinking about the heads right now and was wondering if the 240cc (trick flow or cnc promaxx) would be too much volume.

I see some guys with cnc stealths in this thread so I guess the ported heads would be ok. That leaves me with the possibility to step it up to a large cam and more gear if I decide I want to get more serious about haulin ass...

I'm thinking 3.55 gears are the sweet spot...BUT, I have a 2.94 sure grip in the car now so maybe I would setup a 3.91 third member and if I want to take a longer trip just swap the 2.94 gears in...idk.

2.94's would be sweet on the highway. I don't care for my 3.23's on the highway but most guys wouldn't mind it at all. I had 3.55's and hated them but they'd be better on the strip.

Go for the better Heads so you have room to grow. My motor is a pump gas 500" with CNC max wedge Edelbrock's. It has a small cam and small headers, seems to have alot of torque so I'm hoping to hit high 10s or low 11s driving to and from the track.

I ended up hitting the Belvedere with a 0.051 N2O jet. It ran a string of 10.95-10.98 once I got the timing where I wanted it, before I got a talking to for no roll bar

It had a 10.8x in it, but the track was going away and they shut it down before I could get the launch sorted

Car is 3700# at the line.

I basically use it as a daily driver during the 2 month MI summer...

I have been 9.70 with my 493 at 3300 lbs with 3.55 gears, this combo would have went 9.50s but decided to change directions without ever getting the slip
I have been 9.88 with 426 g3 at 3240 lbs with 3.55 gears

Impressive, sure would love a car like that in my garage.

Very impressive Ray. What RPM do you trap at? 275/60/15?

Im thinking both combos are under 6800. Ive have either 325/50 or 295/55 on my car

Awesome! I thought about doing this for the upcoming season as well. What did you set your total timing at? Did you change spark plugs to a different heat range?

With a 28" tire, 3.55's, and a mph of 136 I'm getting only 6000 RPM's, which sounds about right to me. Are you running naturally aspirated?

I have been 10.91 with 3.54 gears but my 5-speed has a 3.37 low gear so that makes for a nice mechanical advantage. I will be interested to see how the car reacts with a 4.10 gear and a 2.66 low gear in a stock HEMI box.
Last time out I was driving through the clutch which was indicated by the 126 MPH. with an 11.09 ET. Someday I will get my clutch tuned but I don't spend enough time at the track to get it dialed in on kill.

It seems with the torque alot of the strokers have they run fast with not as much gear. And the shorter tires is like putting a high number gear in so that may have also helped keep the et about the same. Ron

NA. My 493 was 140mph. The 426 135
