Is this vibration something that plagues all aluminum drive shafts?

yeah they will fix your wrap up problems.

430 is a great number! I've got the same motor and didnt put down anywhere near that.

Lucille you got to talk to Dan at Masport Speed Shop in Boca Raton he did an awesome job tuning this engine. I'll tell you it was a pain to get the engine running right with almost no sign of surging and good power. I am in the process of getting the Caltrac traction bars to get it up on the dyno again and push it a little harder. Hope this helps you out.

I'm getting the Caltracs so the leaf springs won't wrap and as for the vibration I got the new balanced drive shaft built to handle 3 times the HP that I'm putting to the wheels.
