Tune Up

Tune Up
Just installed new cap, rotor, wires and plugs in a stock 350 (76). Haven't set the timing as of yet, but attempted not to move the rotor when installing it. I have a definite misfire with a bit of engine knock now. Before the install there was no noise or miss. Could this be a timing issue? Or something else? Thanks for the help.

There is no way that you could have changed the timing settings by doing what you did,
HOWEVER, if the cap was made wrong (as above), or if it wasn't seated properly when you reinstalled it, you could be off a few degrees.
Also, if the last guy to tune it up left the distributor clamp bolt just a little bit loose, then you could have moved the distributor a few degrees when you changed the cap.
I'd say go rattle everything around, then put a timing light on her and double check.
