Stock U joints and yoke?

[Steelrat]

I am looking at taking my car to the track, and am wondering if I would have any issue with the stock U joints, driveshaft and yoke I have.

I am running a 488 HP 504 TQ 408 sb
Built 700R4
255/60/15 Mickey Thomspon ET Streets
3:73 gears

Thanks

What size are the stock joints? What rear? What size stall?

On slicks watch out cause something might pop. Do you have a saftey loop?

[Steelrat]

1310 U joints
8.5 rear built to take 600 HP
2800 stall
yes have driveshaft loop

The tires would not be true slicks. MT ET stret Drag radials

I think you are at the edge. With the auto and a relatively mild stall everything might work out for a while.

weight of the car is also important, lighter the better

I am going to upgrade to 1350 U joints. Would I need to replace the yoke? I can find 1330, for a GM 700R4 Transmission, but not a 1350 yoke. Also how do you identify what yoke is currently in it. A number or?
