This is what the timing marks look like on my 216 - It's in a 1937 truck.
So the line between the U and C is TDC? and the BB is 5 degrees BTDC?
I could do the math, but what is the V mark used for?
Jim
Time with the ball right on the pointer. The 5 next to ball indicates the ball (da BB) (O) is at 5 deg BTDC. Which is spec timing.
The UIC is actually "Upper Center" with a hash mark in between U and C. The hash mark is dead nuts TDC.
The triangle/V is a factory test spec mark.
What "math" are you talking about? There is no math involved.
Silverado: Did you get it timed? (Your Hijackers will be persecuted.)
