 I saw this same problem with a buddy with a 302 in a '68 Mustange. It turns out that when he rebuilt the engine he used the wrong bolt on the harmonic balancer (too long). This allowed him to "bottom out" the bolt thinking it was tight when in fact it never came in contact with the balancer at all! (very, very bad).

Luckily we caught it pretty soon after the rebuild and put the proper bolt in.

Just my .02cents worth!

:=ok i have what i belive is to be a problome. i was under the hood today and i found that when i was to rev the engine up my bottom pully (crank) was moveing outward twards the radiator. it was only about a 1/16 to 1/4 inch movement but from what i know this shouldnt happen. the motor was just rebuilt with clevlite77 berings .10 over and trw flat top pistons .30 over using a standerd crank. the motor dosent shake and it dosnt lack any profmance. what would cause this? it only has about 800 miles on it?

Was the bolt to hold the pulley fast to the crank put back on?
Or is the crank moving that much? If it is the crank moving that much, you got a major problem with the (thrust) main bearing installation.
