Yes, it needs help in the first 60 feet.........131MPH is enough to go in the 9.90-10.0 range......  Wayne

I sounds like on the video that the motor goes up to the flash stall rpm of the converter and stays there fur several seconds, until maybe 100 ft away from the starting line  It almosts sounds like it it loaded up the first 100 ft. after the hit of the throttle Do you have a playback tach? If so what rpm does it flash to and how long does it stay at the flash RPM?

The chart I have shows a minimun ET for 131 of about 10.15-10.20 so you are not that far off. And that would be a fully scienced out car with slicks etc. I would only ask him to raise the stall if he can keep the tow torque efficiency and the high RPM efficency at acceptable levels.
I honestly think you are doing pretty good since your car is heavy and you are slightly conservative for street driving (gear and tires). Your car is very impressive.

just an opinion for whatever it's worth. if it's mainly a street car, i'd probably leave it alone. if your going to race it more than you street it, a stall in the 5200-5300 rpm range will net much better results. changing to the auto is the best thing you could have done, all things considered.

If you increase the stall, the car might not hook any more.

3.73 gear??? I would put a little more gear in it.

There are a few unanswered questions. What size converter 9-10"? What was the 60ft time? How about your 1/8 mile incrementals? Cam specs? How do you have your caltracs and shocks adjusted? Air pressure in the drag radials? Cool Roadrunner I never knew they were that heavy though. Good thing you have that big hemi under the hood! Like others have said, if its mostly a street car, I would say you're fine. An 8" 5200 converter will surely pick up in the 60ft, but at a streetability price.

I'd agree W/ this except I can tell you his "rear end guy" won't be re-building that Moser M60 anytime soon again after the last go-round W/ it 
The converter is 9.5" PTC.... Scott has one of those wide spread tachs that does not really start until 5000 RPM, so it's tough to see exactly where it is flashing, I thought I recalled around 5200 in high gear flash test on street, but may have been closer to 4800? Hard to tell with that spread tach.
I'd leave it alone (think the wife would like to hear that as well, less $$$$ just to put new ring gear on it LOL)
I'd just like to see bit shorter tire on it & some much lighter wheels... We'll definitely try my 275 Hooisers this spring....
Get MSD timing retard on it so it will start easier & will be able to do fine tuning of the timing @ track as it seems to be sensitive to timing, & changing it W/out a trigger is a pain.
I'm fairly sure we can find some 10.20's in it this spring with some more passes. Car really does not have alot of passes on it since it went Auto.... at least not good "clean" passes where it hooked etc. Broken sure grip & stripped ring gear took out alot of usefull track time.... & it has not been in "great" air yet.... probably 1500 feet is best it's seen with the auto, so there will be some ET there as well..

Thanks all. Many areas including the driver have room for improvement. It's good to hear different perpsectives such as how well it's doing considering it's overall mission. Since the converter is always so key, and this one wasn't spec'd for me, and is coming out anyhow, I wanted as many ears as possible on the vid. Incrementals: 1.597, 6.731@104.74. Cam is not too big for 540 inches, 259@050, 112 sep. Yes and the weight has been verified. Ryan you're supposed to on vacation

Wasnt you the gentleman that had a bunch of issue's with the MP crate Hemi, that ended up having lots of mis matched parts, poorly assembled etc?
I guess you ironed that stuff out..
Anyways the car looks nice, the engine sounds great, and I wish you luck Sir 
I just finished up one of these Elephant engines myself, and hope to tear up the track very soon 
Do you mind giving a run down on that engine?
Thanks
Bob

I'm back......
& I'm fairly sure your car went a 1.50 or a 1.51 60' On last day @ track. Which is'nt great for a 10.40/131 But it is 4060 lbs & 3.73 gear with 30" tire... can't expect it to 60' like a drag car when it is setup in street trim. 1.50 is not that bad for what it is... I'd like to see it down in the 1.45 range but I think much more than that is going to be asking alot... & so if pick up .05 in 60'.... that will only be good for ~ .1 in overall 1/4 ET.
