Steel vs Aluminum driveshaft

Jeff Lee · 11-22-2010, 05:10 PM

Kip Martin with his 289/210 SS/L broke his aluminum one last year. Borrowed a steel one for the remainder of the race. He said it felt like a slug in high gear. I know it lost a few MPH but don't remember the ET loss, if any. Once he put a new aluminum back in, it was back to it's normal self.
I think a lot of questions need to be more directed at "what you got" and not with blanket statements. 5-speeds seem important to little engines over 4-speeds, same with light-weight parts like wheels & drive shafts.
I have all sorts of light parts. Has it helped set records? Probably. Can't complain about 10.50's in D/S and that's not a little engine.
If I had a 327 like yours, I wouldn't hesitate; 327 is probably about borderline on little engines with 350+ taking over from there.
I do understand budgets though! Could you borrow one?
