Driveshaft...steel or aluminum?
I need to get a driveshaft for my 1957 Chev with LS7, T56 and 9" Ford (3.89 ratio). The engine is currently stock (505 hp, 470 lb.-ft.) but I intend to install a little stronger cam which should take it to about 545 hp & 495 lb.-ft. The engine is advertised to run up to 7500 rpm but I will seldom go over 6200-6500.
What are the pros and cons of a steel vs. alum driveshaft for this combination?

Aluminum is lighter and transmits fewer vibrations, but a steel driveshaft can be stronger.
I sell the PST driveshafts which are warrantied for lifetime and carry a 1000 hp rating.

There is a chart at this link to help you figure out the length you need for your driveshaft. Bob

I went with steel, with the weight of the car and the torque of the motor off the line, I wouldnt go with anything else. DS sold at EPP are great too, i beleive is 0.5" larger diameter then my Denny's 3" steel. As long as the company who makes it is a quality company, the vibrations will not be an issue.

Thanks for the comments guys. I didn't mention that I have a Morrison chassis (pic below) which has a driveshaft loop built in. After measuring everything several times over, I have decided to go with a 3" HD steel shaft because of clearance issues in the loop area. I'll just have to keep my right foot under control.....yah, right

That is a great looking chassis! Bob

We have a nice offering as well in a 3" tube. All we need is a center of rear u-joint to seal on the transmission measurement.
