What is that groove cut in the cylinder and block ?

Re: HIPO GM crate engines
 

Clearance notch for the rotating rod cap is my understanding. Similar to strokin' a hemi engine block...

How hard is it to torque rods and mains? All the fasteners for that matter. Hard to believe there could be this kind of oversight on a target motor, let alone a limited edition ZL1 at a cost of over $16k. I don't get this at all.

On the pan rail; That's for a stroker crank that puts the rod bolt ends out farther...so as to clear with the bigger stroke. https://www.yenko.net/ubbthreads/imag...lins/beers.gif

Now I get it...I saw the notch but you had posted "Not a good sign" so it threw me off. Now looking closer I can see where the rod was hitting it...Must of made alot of racket.

Re: HIPO GM crate engines
 

I have heard about the same problems with the Mopar Performance Hemi crate engines. I wonder if the same company is building those? Many buyers have installed them and then had them spin bearings, throw rods, etc., on start up. The unofficial advice out in the field is to disassemble them upon delivery, check everything twice and then reassemble and install.
