Has anyone ran into needing a crank key? Ordered some from summit and it clearly states LT1/LS1 on the package but, they are only .75 and the slot of the crank is 1.30. Are there different sizes throughout the years?

 

Are you talking length??? They Key has to slide in the Slot to get it in and out its ok for it not to be exactly the same length. As long as when you stick it in it protrudes up enough for the Timing gear to engage.

 

Yes,im talking about length. Summit is sending me a different one so, we will see.
