My car is 3300 lbs with me in it. 5.9 magnum with a 4" crank making 406" hyd roller (limited lift with factory lifters) motor, 904 basicly stock with TA vb with 4.10 rear gear with 29" tires. I had a BTE 9.5" converter handing out a 1.58 60 ft time with a 11.50's 1/4 et in good air and 11.70's in heat. Changed to a TA 8" verter and car went (good air) 1.44 60 ft with an et of 10.92 at 122 mph, (heat / bad track prep) 1.49 / 1.50 60 ft, 11.03 1/4 mile at 119 mph. A good converter will make you think you are in someone elses car, haha. Old verter stalled around 3300 flashing at 4000 or so. 8" is stalling 4200 or so with a flash around 4900 rpm. Buy a good one and you are done with that area. If you buy 2 or 3 cheap ones, you could have had 1 good one and didn't have to pull trans many times. talk to the RB guys and find what is working with your numbers. 
76' Volare, 5.9 magnum w/Iron heads. New best 10.68 at 123 mph 1/4 mile.

MPH is down. I suggest tuning before spending money, ripping the heads off, or doing any other parts swapping.

Now that you provided some more cam info ( exactly where I was headed when asking the LSA), you do have better choices in a camshaft. Especially if its installed retarded 3 degrees? I've said it a gazillion times on here, if you dont 60', you are going to maximize your combination. Its all starts with the 60'. Your still going to have issues with the other items as noted. I still believe the carb is oversized as well.
Dont forget strokers " eat up camshaft " duration, so the larger cam specs arent always quite so detrimental, but a 114 LSA is in your case, and then in at 117(?), thats killing low end power and torque, which also kills torque converter stall and 60'.

Hi T,I want to add some things that we done.I passed a friend's car a BBC and looked at his tack.He was shifting at 5200 I asked is at all,he said yeah it didn't matter if he shifted at 5200 or 6000 same mph or et. in the 1/8. So I was shifting at 6000 and went to 5200 then 5000 down to 4700 and picked 5 mph.Both cars had 410 gears I guess it was in 3rd.
longer .The car had a .555" solid cam.Your car will come arould I think you need slicks.~~ Bent

Is it worth the time in advancing that cam if the duration is to wide? or should i change it out? I don't have anymore info on it then what i've listed. I thought i had the tune down pretty good from the chassis dyno. I did try different launch rpm's and shift points. I do understand that the 60' is critical and until i sort that it's gonna be slow. With a correct cam for this engine wouldn't it be ideal to have the heads flowed? 
Flowing the heads would cost money that you could be putting into the cam.
I would change the cam out with one that has a 106 to 108 lobe separation angle, and a duration at .050 of around 260 to 270 @ .050" lift, preferrably 260 for great mid range torque.
Advance it 4 degrees if it doesn't already come that way (advance ground in)and hang on.
You're converter will stall higher, you won't have to change gear or tire.

I agree with everybody that the stall speed and gearing isn't optimum, but should work fine with 496 cubes. I believe the real problem lies with the camshaft.

I will probaly change my tyres for the strip anyway because i got bit carried away with the burnouts and took a fair bit off my normal drive tyres. I will definately sort the cam area. It's great being a part of this forum the help is fantastic! 
Ah yes, the big Auzzie burnouts eh? Showing off to the Sheila's watching?!  Everyone loves a big burnout! hard on the tire life though!
I think you are headed in the right direction. A set of 28" tall tires for starters. I would look at suspension stuff too. The cam isn't perfect, but I think the combo has a bit more in it. Look at a GM LS7 in the C6 ZO6... it is running 120LSA, and it isn't a boosted or sprayed deal.

The calvert front shocks would help the launch on your car, although one or two guys have tried them
on heavier cars and not liked them.
Personally i love mine.

There's a lot of posts suggesting jacking the camshaft around - yet nobody has mentioned that would be foolish without seeing what kind of valve clearance you have now. Just because it should have clearance with the parts listed doesn't mean it does . Since you don't really know whats inside the motor and are going on the sellers word, I'd stick with tuning carb, timing, suspension, tire pressures etc., before I would mess with a cam degree change that may break a bunch of parts.
Free advice and worth every penny...

I have a brand new big solid roller for a 59 degree small block sitting on the shelf because she no fit. I knew it would be close. Turned out I had about -.005" clearance on the intake valve So, Logically, I bought a second car to build around the camshaft... it's going to be a while before I use that cam. OR we can always use it in a customer's car.

The exhaust is Hooker supercomp 1&7/8 into 3' full exhaust to the back bumper with 40 series mufflers. Will get a set of 90/10's and try that as well.
