small yoke driveshaft...would you trust it?

[dwbiggs]

With the combo listed below...would you trust a small yoke to handle the HP and drag radials on the dragstrip?  This is the original driveshaft from the small block setup.  Also, will an 8 3/4 489 cone style rear hold up with drag radials?

I ran my stock small u-joint driveshaft in my Challenger to  11.80's with the juice and 10 inch slicks with the front left tire about 6 inches off the pavement. But............bigger has to be better.

[Moparal]

Yes I would and have. The driveshaft would probably fail first. It's better to go bigger tho. And you can buy solid joints too if you want. But for a safety concern....It's Christmas time so what's Santa bringing you?

Most fo the truck Danas use the small 7260 yolk , But I will still prefer toi have the 7290 joint in there

I've done it too. But, when possible, I'd upgrade.

use it till it goes...if your concerned not that it would be a bad idea for a drag car or any car add a ... crap one of those thingies that the drive shaft goes thru that keepis it from falling and getting launched thru your bottom.... Safety Loop?  I think they are called..I imagine someone makes them for the E-body, if not you can buy or make a universal.

Us car tool / John has a nice driveshaft loop that bolts to the trans cross member

[TreeFrog]

thereya go!

[Chryco Psycho]

same piece

[dwbiggs]

dunno if that will fit...my TTI pipes run very close to the driveshaft.  Guess it depends on how big the loop is.

[moper]

You may need to modify the exh to fit that loop with TTi stuff..

[dwbiggs]

Or just tack a strip of metal between the pipes.

Make sure the pinion angle is correct , it should be 4-7* nose down from the driveshaft , having that set properly takes a LOT of load off the U joint
