The weather finally came around, and gave us a few hours to run the car before rain showed back up. Was able to run the car three times. First two were shake down runs that I shut it down half track. The entire car is new and I had no idea what gremlins lie in waiting. The only video the kid was able to get was of the second pass.

Running a two-step off of a line lock. Only launched at 1800rpms instead of the 3500 it is built for. We'll be goin back this Wednesday to play with it more. But it's obvious the Mopar drag shocks are getting way over powered. All week I've been in discussion with the guys at PST for some double or triple adjustable shocks.

Anyway, third run was 10.99 as I short shifted the first two and hit the rev limiter in third before the end of the track.

Didn't look all that bad to me although some decent double adjustable's will be of at least some additional tuning......if you had some then you could try tightening up the extension some on both the front and rear as there is substantial movement from that standpoint and may not be needed to that extent.
 
Still on leafs and shackles ! Nice car and nice pass !!

Nice looking car. Any details on your setup.

440 stroked with 440source 512 kit. Victor intake with 950 quick fuel carb, mad ignition. Precision 3500 stall, manual valve body 727 with lots of strong parts, 392 gears in original 8 3/4. SS springs with snubber. I have a 150shot kit sitting on the shelf I might put in this winter.

Car weights 2985 with me in the car. I need to get it on the scale at the track to be sure, as I used a big animal scale before.
 
Thanks. I have a lot to learn about setting up shocks. That's completely foreign to me. Looks like a four week wait for them, so I should have time to start studying up!

There are multiple brand name D/A shocks that would work perfectly fine with the scope of your car........Vi-King, Strange, QA-1 etc. I have run the Vi-King's before when the car was at an earlier stage and they worked for me.

You might consider as a future upgrade changing over to Cal Tracs with the mono leaf and lose the SS springs and pinion snubber if for no other reason a weight savings.

the car will likely run pretty much identically where ever you launch it from, be it 1800 off the foot or more rpm elsewhere. You have what sounds like a 10 inch vert
not so sure with that compared to an 8 inch
Launching at a higher rpm( especially with leafs) generally isn’t gonna make the car any faster( if as fast) as it “ tenses up) the suspension and gives it less room to work.with or without a brake.
I had a 9 sec 3350 pound car on 002/003 leafs that went 1.34 60 foot at 2k foot breaking or 3500-4200 rpm off the chip and T brake. 28 by 10 tire. Same ET either way.
Usually leaving at a lower rpm will slap the vert harder and plant the tire better. That all said, every combo is different.
Plenty of guys on here who can help, great place for that
 
Looks good man. Sounds good but you have some

Looks good, sounds good. You'll get it sorted out.
 
Great looking and running car!! Congrats to you for getting it to this point. Enjoy the heck out of it from here on!!
 
Take your entire rig to a certified scale at a truck stop, weigh the entire rig & then weigh just the truck & trailer. Be sure to get the "certified" weight slip. Just be sure you weigh the car with a full tank of fuel, your race suit & helmet as well as the driver being in the car.
 
Nice work, OP. She's a ripper!

If you REALLY want to dial this car in, borrow or invest in a set of corner scales. That'll allow you to see the weight distribution for all 4 corners, and then you can add/remove weight where it's needed until you find the right combination for your car.

And then if you add Caltracs and monoleaf springs in the future, you can set the preloads on the scales as well. Not the cheapest method, but it is scientific. You can do it all in stages after you source the scales.
 
You guys are good at deciphering the time slips. Maybe you can give me some pointers on this one. I'm still trying to figure out the shift pattern, as with the 727 with 392 gears, it seems at one point I hit the rev limiter on the 1st and 2nd shift and then again as I crossed the finish line. I'm sure the engine could be pushed a little further but wanted to keep things on the safe side, shifting at 6,000 with a red line at 6200.

The 60ft is actually very good for the rest of the numbers, and everything else lines up quite well.
Wallace says a 1.53-55 is about right for 11.00
