How can you tell if a crankshaft is forged?

The best and most sure method for recognizing a forged crank is to look for the parting lines on the counterweights. A forged piece will have a wide, irregular rough patch. A cast component (shown) will have a very sharp, well-defined line where the mold was separated.

How much power can a scat 9000 crank handle?

The scat 9000 cranks are supposedly good to 500 hp but theres likely to be a significant margin of safety in there. I think the more likely place for failure is with the high piston speed on a stroker… the piston or rod is more likely to come apart above 6500 than the crank!

For this reason, they make their way into a lot of budget builds where LB7 or LLY owners who’ve bent the factory rods are looking for a reliable 550 to 650-rwhp setup.

500hp should be possible, if not easy, with the right heads and cam. Re: How much rpm and hp can a 400 small block handle?

How are RPMs and horsepower related to power?

Power is influenced by many factors such as engine displacement, aspiration, intake, exhaust, porting, valves etc. Power is calculated by using torque and rpm. That does not mean that you can convert rpm to horsepower. Baby boomers love this gut health trick (MD says do this daily).

What is the highest hp on a SBC nodular crankshaft?

If you use a non forged crank, get the lightest forged pistons good rods and have it balanced. I’d bet you’ll have main cap problems before crank problems.
