the sound of cams?
k well i am trying to figure out what cam i have and i was wondering if it is possible to tell by the sound of your engine. when i put my car in gear it sounds amazing (mean as hell)! just like how zepher (sp) car sounded in that video he made. any ideas?

1. Find TDC accurately (i.e. ignore the timing mark)
2. Put degree wheel on balancer
3. Put dial indicator on push rod end of an intake rocker
4. Adjust rocker tighter until push rod stops moving (lifter bottomed)
5. Rotate crank, note degree readings for valve events - .006" & .050" opening, peak, .050" & .006" closing; note peak lobe lift
6. Put valve adjustment back where it was
7. Repeat for an exhaust valve
8. Compare to cam spec book
Alternatively you could remove the rocker entirely and put the dial indicator on the push rod end itself.

step one...remove cam
step two get the dial and learn how to use it
step three put cam back in
step two get the dial and learn how to use it
step three put cam back in
you make it sound like the task is as easy as pumping gas when its not self-serve.
haha

Have you tried to ask the previous owner? I assume there was a previous owner or else you would/should know what cam is in your own car...

i've done many cams, motor in n motor out. Its easy but time consuming but hey, theres a smartass in all of us.
There "is" a way you can tell by the sound, its the most easiest way yet.
But your name would have to be Miss Cleo =]
