Dan Juday Posted January 2, 2001 Share Posted January 2, 2001 Is anybody running an aluminum driveshaft? The wrecking yard I got my motor from,(305tpi out of a '91 Firebird) gave me one from a Corvette in the package. I thought, "this is cool, better parts for free". Then I read some posts here that worry me. Mikelly heard about them failing in cop cars. Another guy had clearance problems between the hand brake and u-joints. The aluminum shaft is larger, 3" dia. If anybody knows about them let me know before I pay to have it sectioned and balanced. Dan Quote Link to comment Share on other sites More sharing options...
Modern Motorsports Ltd Posted January 2, 2001 Share Posted January 2, 2001 Ron Tyler ran a custom aluminum one he had built at a place with a high speed balancer (not common at all I was told), his car I've been told be quite a few now was the smoothest V8z (Lt1/T56) they'd ever ridden/driven. My father now has his powertrain and will finish his swap this spring. I know the high speed balancing can't hurt but the lightweight alum. has to help a lot as well. He also swore by his pricier GM motor mounts that he felt were of a superiour rubber to the generic Sealed Power and others etc. Just passing that on..

John Scott Posted January 2, 2001 Share Posted January 2, 2001 I know Hybrid member, Rob, has been running one. My driveshaft shop said there were fewer harmonics with the aluminum shafts and ran truer. A bit more pricey, too. JS Quote Link to comment Share on other sites More sharing options...
