well I took the camao out yeasteday in 110 degree tx weather and I was getting on the highway and was pulling her to around 5k rpm and bang I hear like a backfire from the motor then I look at the gauge and lost all rpms and she just stated coasting I pulled out and waited for her to kind of cooldown put she would neverstart....this has to be the Optispark right?

It doesn't have to be, but it might be.

yep yep, thats what happened when my opti went out. Was driving along and then the gauges died.

I was driving up a hill when a spark plug wire blew off mine car and it went dead.

It was the icm for me.

That is the exact same thing that happened to me when I was driving down the highway then all the sudden you've got nothing no rpm's or anything and it turned out that the opti pretty much exploded on the inside when I took it apart.

well so this is what im getting .. got the OPTI from the parts lady on ebay with a msd cap and rotor and got a oem timing chain because i know its never been changed. i already rebuilt the whole top end just hope the bottom can last.. has 143,000 miles.. looking for a longblock shorty

Good luck man, I got and opti from the parts lady, but that was before MSD had anything available and its been holding up for about 3 years (knock on wood) and I spin mine to 7k rpms, just be sure to locktite the rotor screws

I'm leaning toward the Opti more than the Timing Chain.

Atleast it wasn't a Rod..

while i have it apart might as well do some other stuff...have a small leak from the timing chain cover anyway
