Other then the LT1 cam has a pin for the opti, is there any other difference? Is the hole for the pin also on the SBC cams?

Thanks
Jeremy

 

You can use any sbc cam for 86-up hyd roller just install the longer dowel pin, however make sure you get something with at least a 112 lsa or the computer and emmissions won't like it. The difference between our cams and traditional sbc cams is the nose of the cam is different to accomodate the cam retaining plate.
