Quote: Prosport not to high jack your post but do small blocks have the same problem, my timing seems to bounce a little ? can this trick be done on the small blocks ? i have play in my shaft up and down, so wouldnt that cause the timing to jump all over being the drive gear could move up and down on the cam gear. i have a rollmaster timing chain and a tensonior on the 416 so it cant be jumping from there. thanks Bondobob
The SB drive is on the other side of the cam, the rotation of the cam is pushing it down already.
If the tang on the bottom of your dist. does not fit tightly in the drive slot that slop could cause your timing to move back and forth a bit. If it's quite a bit you can weld a small bead on the end of the shaft and the grind it back down untill it fits perfect or if the slop is not much I have just peened the corners of the tang with a few raps with a hammer (carefully) and it has gotten the job done.
