I'm not sure I'd expect a anything less from a stock, not purpose built engines.
I'd be curious what coolant and oil temps were when all was over.
The engines I race now were designed for reg and turbo.
The rods are certainly bigger/wider than I woulda expected for a 4 cyl.
After a hard season of hundreds of laps bouncing off a 7500 chip, it just pounds the snot outta the rod shells.
The shells had "crush" everytime I put them in, they literally fall out after.
I always say "if you try to blow'em up, - you will" .
Heat is the big enemy here, and hi expectations, lol.
Wonder if alum/silicon shells would take heat better ?
King bearings says closed permanently.
