Aluminum or steel driveshaft ?

[big gear head]

I'm using a Strange steel shaft in my car. I used several Inland Empire Driveline shafts in customer's cars over the years. Denny's and some others are nice too. Aluminum is nice, but more expensive. Go with the 1350 joints. You'll need to swap the yoke on the rear end and get a new one for the transmission, but it's worth it. Be sure that it's high speed balanced. The M20 won't hold up to that much power if you use slicks.

Been looking into driveshafts for this and the length is an issue with critical rotational rpm. The shaft, itself, will be about 58" and at that length and a 6500 rpm speed, Denny's is the only one who will touch this. All the others drop out at about 52-4" for that rpm.

I just talked with their phone rep and I will, most likely, be ordering their 3.5" nitrous ready pro package with Mark Williams yokes on both ends. Their 4" aluminum isn't all that much more, but since I need new rear gears and stronger axles too, I'll stay with the steel. Thinking about Mark Williams for the gears and axles too. The Strange gears for street/strip warn they are susceptible to teeth breaking under heavy shock loads and not really suitable for drag racing with slicks...hmmm. I don't need to break them next, so will be talking with Mark Williams about their street/strip gears and axles soon.
Need to decide if I want to modify the axle tubes for bolt in axles first...

X2 you will be taking it home in a Dixie cup . Clutch management will help but?

As far as the driveshaft the aluminum is easier to accelerate as its rotating mass, my T/S car was faster with aluminum

I have a Denny's HD steel driveshaft in my 67 Camaro and it has taken everything my 525 hp 406 has thrown at it with no problem. Lifetime warranty on U-joints as well.
