I have three lt1 cams, they are all for sure 95+ vented opti ones.

But I have no clue what type of car they came from. (impala, camaro, etc)

Is there any way to tell by the part numbers on the cam?

One says GMPT 242 15
One says GMPT 242 17
Last on says GMPT 600 15


I need one for my 95 Formula

Thanks
Steve
