Take your time and look at everthing closely,My times started slipping I thought of everthing mentioned here, I just put it off as a crappy track prep, Yesterday I broke my motor, Rod thru the pan, water/oil mix your know what that means, Trust that little voice in your head if it isnt right don't run it.

I know if they are reversed it will usually mess with the timing. Light travels faster than the speed of sound,,,this is why some people seem bright untill you hear them speak.

I use this as a diagnostic tool- 8 sec. car...one gal. in 15 seconds;9 second car in 20 seconds;10 second car in 25 seconds;11 second car in 30 seconds;12 second car in 35 seconds. Hope you find your problem

Verify your timing mark and lock out your distributor .I had a harmonic balancer that I could could grab and twist the outer case on ,,I think it was a TCI rattler . 6.50 @ 226 MPH 4.25 @ 186 MPH https://www.youtube.com/watch?v=YX86DHGKBo0
