Old school timing light vs digital on a 350 Chevy and I got two completely different readings
Tried both on a buddy's 1978 C10 last weekend and the old light said 8 degrees while the fancy new one gave me 12, has anyone else run into this kind of mismatch between tools?

Old school timing lights don't lie. They're simple - just a flash and a trigger. Those digital ones have software bugs and cheap sensors that give false readings. Seen this exact problem at the shop three times now. Trust the old light. The 8 degrees is what that 350 wants, not the 12. Digital stuff adds delay or reads harmonic balancer wobble wrong.

Bet that old light's calibration is just as off from years of being dropped on concrete floors.
