This is how l have done ALL of my engine the same way and never any problems.

I found the piston that let go in my beloved C6BBT7. The engine was bought used with ceramic bearings on Ebay for $150, engine ran great for over a season. I don't run my engines lean, it just let go on a small straight without warning. Im not complaining It was one of my best engines, I miss her.

I think the rod is still good!!
