Not at 7000+ rpms. We're leaving the line at 7800 rpms. Our super vic is straight out of the box. I'm using it not because I felt it would make more power, I'm using it because I already had a 4150 style tb and it was cheaper than a fast. It did trap 132.75 mph this past weekend though...crossing the traps at about 7700 rpms. 
I just can't figure out how our 60ft times are only about .05 off the top cars which are also both 6 speeds and we have turned in the best mph on the list but somewhere we're giving up 3 tenths?
I'm hopeing we can get into the 10.30's with a few changes and some decent air would be nice...

For example one car runs a 1.5 60' and traps 120mph and runs a 11.0, but another car runs 1.5 60' and traps 120mph but only runs a 11.2... how is it possible if MPH stays the same? There must be another variable, but all of them I can think of would just increase the mph, which in this example is held constant...

whooo, thats some rpms 
alvin was saying some things about you guys testing on the dyno beofre the shootout. There was like 40whp in the exhust setups!! whats the dyno chart look like? You evern try shifting it lower? my car like it.
congrads on that mph thats really fast

Tick, what does the car weigh? Smokin01's car was a real potato chip, like 2800 or something like that if I remember right..
What are you running for a tire also, he was on a 28x10.5S tire.
You may, need to try short shifting it or something like mentioned, the mph is great and is on par with what you need to break the record, but the car needs to be ultra light, and needs to really leave hard, really hard
Couple super stock guys told me a couple tricks that I found worked pretty good, shoot me a PM.

I don't have the slips handy but the 1/8 mile this weekend was a 6.73 @ 102.xx on the 10.50 pass. I've had the car 60ft as good as a 1.41 at the local 1/8 mile track which also yeilded a 6.71 @ 102. The DA both nights were about the same.
We found probably 40rwtq but it was in the midrange...a range which we probably never see with a manual tranny launching like we are. The torque was really low for this setup anyway...it only makes around 360 rwtq which I probably blame the 2" primary headers for. I think peak power was over 7000 rpms but I don't remember exactly and we're shifting at 7400.
Just over 3000 lbs and 28x11.5 ET drags. As mentioned, our 60fts suck right now. They are really inconsistent as I havent figured this clutch out yet. I had it running 1.41's all night two weeks ago but then it goes 1.47's all day Saturday again with nothing changed.

Are you catching the 60' beams with the rear tires everytime?

The biggest hurdle in getting the stocker to live at those rpms is keeping the bottom end oiled... We've probably got 20 passes on it leaving off the two step at 7800 rpms every time. I'm sure it may let a rod fly at any minute but we haven't had any valvetrain issues show up on the dyno or the track...

Jonathan, interesting your point is about keeping the bottom end oiled to have it live at 7800.
Do have have a dry sump in there? Do you do anything to restrict the oil coming up through the lifters?
That is cool stuff right there. 7800, DAMN!
Nice work.

I can't give away all my secrets lol...but its not a dry sump. Its nothing special...just regular stuff anyone can buy. 7800 rpms sound crazy, but how many have actually tried it? FWIW, I haven't ever seen a rod bolt let go in these engines, but I have seen a few rods break in the middle of the beam and appeared to have spun the bearing. My theory is the bearing begins to spin making a pass and before it has time to truely spin and start knocking it just siezes up and breaks the factory rod... My car almost burned down once because a rod let go this way and oiled the bottom of the car up which the headers then lit. Keep the oil going to the rods, and turn the **** out of it.

Dose the oil filter screw on the the oil pan still? Did you go to sam johnathan, and doing there old oiling mod?
Did you do anything to the intake, I havn't goten mine yet but off the specs, its quite a bit bigger then what the head would want. I'll probally put some epoxy into it, I'll see how it dose. Car is flyin' next time shift it lower and see what it dose if you havn't recently, mine gose faster?
