Short lived 68 Z28

Did your dad remember having had the long block replaced in the 68 Z? The entire engine looks like it has no paint, the oil pan, waterpump, and balancer all are painted orange which leads me to believe it had a long block done and with 5.13's I can understand if it did...

I noticed that as well. He has never mentioned it but the things they did under warranty back then it wouldn't surprise me. See the &quot;warranty replacement&quot; short block in the 396/375 Camaro. There was nothing wrong with that engine at all other than the owner wanting a 427. Was put in at the dealership.

On the flip side, I do know it was a two bolt block as he has commented on that as he feels the 4 bolts really were not necessary and spun the 302 up to 10 grand when it was in the Nova with the roller cam, rev kit and tunnel ram.

I'll ask him about it though as I am curious as well. I know the top end had been off the engine as he ported the heads but no idea why the block and heads would be bare.

If it had been vatted or replaced is the only reason I could come up with...
The replacement idea came from a thread on here where it was stated warranty engines rarely were painted the correct color if they got painted at all... some of the service guys said it was based more on if a random can of engine paint was laying around. &quot; they didn't get paid to paint engines... just replace them.&quot;
