Success! There's a couple of guys on Q&A (right now) who are having difficult balance/vibration/noise issues.

I've been told there are 2 balancers for the driveshaft,low & high speed.Marty at SUPERSHAFTS http://www.supershafts.com/ has the highspeed and claims it is better than the lowspeed one if you race,especially at high RPM.
HEMI-ITIS has no cure. My condition is fully BLOWN!!

That warped thing is a little disturbing. Is it a stock type shaft? If it is, you are starting to push the limits of it as it is trying to "jump rope." Time to step it up to C/M! My bad, out of round by .008-.010 and enuff to shake the dial indicator pretty badly and also needed ft. weight w/a couple welded on washers. I will install it after business stuff then test maybe later or tomorrow.............. It is CM w/1350 spicers

At 15 years, yes you Most likely do need one. Change it while the shaft is out. As I recall it wasn't that hard or expensive. 15 bucs maybe ,if that.
Well unless the shaft is in already. If it is you can still grab front driveshaft yoke and move it back and forth to see how much play you have.

I have the same goal as you Thumper, hoping to get a 5.99 or quicker ET with my pump gas small block. I believe with some of your carb tuning on my pig rich 1050 Dominator I would be a lot closer to my goal. I am looking forward to your next outing to the track to see your improvement.

Dom, you've been seriously thrashing on the Dart. Physically and mentally. I think your efforts will pay off with big returns. I'm going with a 5.95x, but I want to see pics of the time slip and track security escorting you off the premises.

Been hacking away at THUMPER forever but lately the results and issues I have found should help me fly...........5.95 is a stretch so I'll say 6.000 @ 112 w/a 1.31 60 ft.............I did drill relief holes and they helped but the faster we go the LESS air opening needed just look at an Indy car or old Pro stock cars. I may go w/a 2 1/2" cowl to stiffen the hood and the top will be the bottom in my case forcing the air right into the carb which I have seen done on some fast cars..............It is faster and smoother than ever so next thu. we'll see.........
