Engine rebuild options/advice

[vipercommand]

Long story short, couple weeks ago my 2013 SRT base (~15k miles) started to make a nasty lower toned squealing noise. It happened a few minutes into a short drive across my small town. I limped it to a local independent shop. Oil had lots of copper flakes in it, cylinder 8 had a loose rod, and thankfully the sleeves and top end looked good. No immediate internal damage concerns, until it comes completely apart by my builder. It was at least 3 quarts low on oil, and I do my changes every 1500 miles (OEM mobil weight). I suspect the rings ate too much oil, rapidly, potentially causing this failure.

Time to rip it apart, clean, hopefully not machine, and rebuild. I want to get beefed up internals for longevity and a potential future procharger build.

My question: Any advice on internals parts to buy for this rebuild to would be greatly appreciated.

I'm looking to Prefix coated rod bearings, pushrods, and lifters. I am unsure if there's any **** rods, pistons etc. that'll help make the engine run more efficiently.

Stock parts are probably going to be the most "efficient" pieces. That's part of the give and take with building for more power down the road. Forged stuff tends to run on the looser side because of the thermal expansion. Cast parts can hold tighter clearances through a larger temperature range and the thinner ring packs with higher lands are going to keep more of the combustion above the piston, though at the cost of strength if you really want to beat on them. I think the gen 5 stuff might have been forged from the factory though, so could be a "best of both worlds" situation to some degree.

I know on my gen 3 rebuild at least that the forged internals I ended up having to use after my last rod bearing and subsequent rod failure are a lot noisier on startup than the old stock parts. It rattles pretty noticeably when cold, but generally goes away within a few blocks of driving.
