Should have no problem breaking into the 9s with that setup now, especially with a more stout bottom end. Happy to see you're making some progress man. Looks great 👍👍

Thanks iron worker!…and I went forged fingers this time.
Do you think it was the piston that let loose last time or the rod?? Rod looked to me like it took the most damage. They also looked pretty thin in the cross section. I know Carillos have handled probably twice what you put at em, so maybe material flaws? There has been a slew of Motorsports cracking recently it seems too though so who knows. Let's hope I get lucky with mine! Should handle the 800 or so I'll put to them I'd like to think. Especially with extra oil cooling and way more air than fuel. Again, truck is looking really good man, must be a great feeling having it come back together after a failure like you had!

I really don’t know but the way the piston or what’s left of it had broke right down the middle looks a lot like how most of them break. But it being right at the top end of the track it was well over 4k rpm… i ended up going with a 2020+ oil cooler this time to try help oil temps a little.

I had read on here , that Fingers had said major temp swings play a big role in cast piston longevity. Along with high cylinder pressure, obviously, but the oil temps seem to be a key factor. Same here with the 2020 oil cooler as well as LML piston oilers and a Derale remote cooler. I had them top coated too. I should be getting my engine back fairly soon actually. I'll be posting back in my thread once I do. If I had it to do over, I would've just sold these and went right to the oval bowls as they're one hundred percent proven thus far in cast or forged. Keep up the good work brother! 👍
