Review on ⏱️ Enhance Precision with MSD 8985 Timing Tapes - Perfect Timing Solution for Optimal Performance by Steve Stone

Used with professional products 80009 7.5" Ford FE Harmonic Dampener on a 1963 Ford 427 FE. Before applying the decal I lined up and looked at the indicator mark 0*. Everything looked fine After sticking the sticker I saw that this sticker is good for measuring 0-20* BTDC time with no more than 1* After that the readings start to deviate from the damper marks It differs by a few degrees at 60* but it's totally unnecessary for my application or pretty much any other application, good enough and MUCH cheaper than losing $250 on a new damper.
