For every Scat crank someone breaks, there are probably a 100 more running fine.Nine times out of 10 you break a crank, it wasn't the cranks fault.
Usually heavy detonation, weak mains, loose clearances, or just plain abuse is the cause.
I have a 383 with a Scat crank and STOCK rods in a LT1 that has been together for 3 years plus, and it gets sprayed with a 300 shot pretty regular. Just goes to show you that you can't always put the blame on the parts, maybe the tuner or driver?
I also use to run a stock, 400 cast crank in my old 406. It saw 7000 shifts on the track, and even when we put too much compression on the stock rods and they pretzled, the crank survived. Junked the block, cam, pan, one head.. but the crank was still in one piece (didn't pass Zyglo)
Usually where the cast crank has problems is on open road, sustained high RPM use. For the occasional strip pass, they hold up just fine.
So far as the original question, decide what you want so far as HP, and your budget, AND whether you want it to pass the Houston emission test.. then spend your money. Anything bigger than a CC305 will be a challenge to get past the roller test. And your 94 has to pass the rollers if you are in Harris.
