Has anybody made a hatch mark on their harmonic balancer and added a pointer on the upper side of their XK engine. It is odd that the timing is underneath the car and you have to keep going back and forth to see where your timing actually is. I have a petronix without the veneer caliper click adjustments.
I propose that I put the engine at TDC manually turning it over and then making a mark on the balancer and somehow welding a pointer to the block. I would then use an ADVANCE style timing light to dial in whatever timing I desired. Just as long as both marks aligned and the dial on the gun was set all would be good?
