SCAT 9000 Limits

Could well be.
The Eagles, while not my 1st choice, are what ended up in the 357. It's still in the shop waiting on more parts. I'll have a look.

Cheap Scat 6” rods. Probe forged flat top pistons. I wasn't surprised when it finally let go. It was well balanced and carefully assembled, and ran Fitech fuel injection. When it was refreshed and the bigger cam/heads/intake went on it just got a bottlebrush hone and new rings and bearings (a lifter had failed prompting the refresh). Journals and bearings still looked good when I pulled it down despite the broken crank.

I did a 347 bracket race engine for a customer, 540 hp, launched at 5500, shifted at 7000. Used a 9000 series Scat crank. He lost a power valve and didn't realize it, washed the cylinders down, so we had to freshen up. Found a cracked rod journal when we magged it.

That was pretty lucky. Usually a cast crank fractures and then fails shortly there after. Unlike a steel crank that can fracture and continue on for a good long while.
