hummmm, the distributer that i designed and installed into my 5-0 (235 chevrolet)wobbled also, but after torquing the clamp bolt down tighter it stopped. i need to pull the distributer out and check it for wear. (the radiator gave up, so the pickup is waiting for a new one from american classic) The original distributer did not wobble at all. (also the dimensions for the distributer on my website are inncorrect, and lastly i would not build another like it... too much machining.. there is an easier way, and i'll find it. my 5-4 (270 GMC) needs one also.
