this is probably not the problem in your case, but, i had a 69 440 that jumped all over when timing it. with similar distributor issues, the car had gear-drive timing, so that was no concern, it all seemed like an electronic issue. well it was a bad harmonic balancer, i am not sure how you could visually check that, but i found out about 6000 rpm and several pieces of balancer ring later, that was my problem. a very dented k-frame, but mostly lucky not to have a hole in the hood or fenders. needless to say, if the timing is not stable, my first check is a new or different balancer. tom 65 satellite --- Robert neal zimmerman <northwestweirdo@xxxxxxxxxxx> wrote: > > then again isnt another sign of a worn chain is that > your timing marks > will be hopping all over the place? > neal zimmerman, eugene oregon > > -- > http://www.fastmail.fm - I mean, what is it about a > decent email service? > > Your free subscription is supported by today's > sponsor: > ------------------------------------------------------------------- > Erase wrinkles without Botox!
