Newly Rebuilt 351W keeps losing timing

[tcrist]

You could also scribe a line on the base of the distributor and intake/block (an alignment mark so to say) after it is timed. That way when it starts to run funny you can just look at the alignment mark and see if the distributor has moved. If it has you can just move it back and look into changing or modifying the hold down clamp.

Edit: chanmadd, Are you thinking that would then hold the dist. from moving. Almost like pinning it?

Zacctly what I did on my street car and race car, easy to do and easy to check, and it you have to pull it for some reason, you can always drop it right back in and be on the $$$$$$$$$$.....
