This discussion was helpful. I have somewhat the same problem with a Romac balancer not lining up with the timing pointer @ TDC #1.
Question 1: The OEM timing pointer I have has a round peephole, a half-round notch, and a straight edge, from bottom to top. I installed it on the passenger side of my front cover (351W-based motor). That is right, right?
Ques. 2: When I roll the motor around to TDC #1 on compression and get the air pressure against my finger, I then insert a straw into the spark plug hole and carefully rotate the motor until the piston is full up. I assume that is true TDC, although the cam I have is fairly radical and may affect this a bit.
When I check the balancer, the BTDC marks are almost over on the driver side at about 1:00. The timing pointer is about 11:00, so I'm off several degrees of rotation. Is TDC for timing purposes when the piston is all the way up, or when the compression is still occuring (pressure against the finger)?
Looks like timing tape may be my solution. Thanks for any help.
