Hi,

I have a 67 cloned out as a Shelby GT350 with a C4 built by Redneck Transmission to handle up to 600hp. I am putting in a Ford 9" rear end, anyone know about where to get aluminum driveshafts? Is this worth it? The engine is new 5.0 running around 500HP. thanks, Bill
 
AL driveshaft is lighter, of course, so spins up easier I'm sure - minor point there. Less vibrations at high speed. But it takes up more space in the trans tunnel, which is not an issue for you but could be an issue with convertible owners like me. I say go for it if you've got the $ to spend.

Many thanks for all the info. I had heard about an aluminum shaft shattering. I have a driveshaft loop installed but wondered if the HP may be a problem. I think I will check with the maker before sending the $$$

I ran 3.5 al for a while with 500 hp and slicks. Seemed fine for me, but that may be different for you if they have a trans brake in it. I've gone 3.5 steel for the new stuff, it IS NOT fun to break driveshafts.
 
I bought mine from Mark at Machine Service Inc. $300 to me with solid u-joints installed and a larger diff, yoke.

Couldn't beat it. He tells me it will take 500hp and slicks all day long.

His number is 313-388-7166. It was to my house in 3 days after I gave him the measurments.

I second this. I am very happy with my purchase from Mark, which ended up being $323 with shipping to PA. That included a new pinion yoke, new U bolts, and a new tranny output yoke.

RH gray slipper available at an additional cost. LOL

My driveshaft has the 1330 spicer U-Joints and is based on a 3" diameter aluminum shaft.

I called there on May 22, 2008 and asked for Mark. He was on vacation and Machine Service could not get me accomodated as quickly as I needed. The guy I talked to told me to call Shaftmasters.

I said that I already tried one of those products and neither the pills nor the vacuum pump did anything to add inches to my unit. He said that he was talking about an aluminum driveline, not a "3rd member" enlarger pump. "Oh, yes, of course. That's what I was talking about too," I stammered. "I don't use those things. That's not my bag baby! I already have a major unit."

Shaftmasters, alum driveline makers, not to be confused with the maker of vacuum pump units for your unit, can be found here

I gave them the specs on a 3 inch alum driveline and asked for 1350 pinion and transmission yokes. It shipped the next day.

The driveline was $267 and $50 for each of the yokes. David took each of my calls and replied in a timely manner to each of my emails. All I have to do now is have it installed.
