Here is what I have, quick and easy:

Built ls2 with what I was told a 58x reluctor wheel.

Well engine starts runs real rough and someone said make sure the reluctor wheel is correct for application.

After taking pictures and looking at it, Im convinced it is a 24x reluctor wheel...

Please opinions on what you think.

1st pic is reluctor wheel seen through the crank sensor hole

and

2nd pic is my reference to which is which by lingenfelter.

Thanks guys

 

FWIW the crank sensor is black...

 

That's a 24x reluctor and a black sensor is the correct sensor, the 58x sensor is gray.

 

I was told about the sensor being black for 24x and gray for 58x. Thanks for clarification, I was swearing it was 24x also but person that built it told me 58x by mistake or whatnot I don't know.

 

No problem.....good luck getting her running!

 

I agree, that is a 24x reluctor wheel.

Below are more images of the 24x vs the 58x to help show the differences.
