So i pulled out the engine yesterday to find the number 6 rod snapped and a little pin hole in the drivers side of the block. Found a 98 engine out of a z28 for a deal-i know i would have tpo use my heads (which are okay) and intake, but is there any difference on the cam,sensors,etc???

That will give you a lot of info that your looking for.

 

Im pretty sure that there not the same. I think the 98 has diffrent piston sleeve size.

 

Bolt right in

 

It will work,but be aware of the 98 rod bolts. While you got the motor out drop the pan and replace them.
