Do you index the flywheel the same way as with 260 electronics? Find TDC rotate counter clockwise 150 thou and the set pointer at 25 degrese.

The timing on a 280 isnt adjustable. Its controlled by the ecu. All you can do is set the air gap (crank position sensor).

I had a bad hole on my stock 280. I had a new 280 power head with 260 electronics with only 2 hours on my Ally drag. I have pulled the 280 power head off my drag and put it on my stock 280 for my Cougar. I put a strong 260 that I had back on the Ally.
