I am gathering parts for the Charity case motor . I Have a nice Two bolt block that will be linehoned with splayed caps , I have a nice set of Crower rods ,My next piece will be the Crank. I am on the look out for a steal crank and i am wondering if there are better castings ( forged ) or better years of forged castings . typicaly the earlier the year the better the metal. What is the optimum crank for a blown alky set up. i want a conservitive motor - so i believe a this will fit the bill . any help or input would be appreciated !

It sure isn't anything Chevrolet made.
Callies, Lunati, Crower.
Below that.....Scat 4340.
Maybe Eagle....but given choice Scat.
Howard I dunno.

Not what you wanted to hear.

No love for China here but still stiffer than the Chevrolet. I have got 2 scats out there in Blown Gas and they are living good. Not flexing and taking main bearings. The Chevy cranks just flex too damn bad especially the last ones they did. The best Chevy crank was the "purple" LS6....still way shy of Scat. Just stay away from the Chevy cranks as it isn't worth it.
Cstraub has deals on Scat. I have bought a couple.
I suggest you fit the mains at .0035 on blown alcohol.

Hey Lucky
aftermarket would be better,, I think the order of importance is ( in blown alk motor is ), rod's , wrist pin , piston , crank , ( and this just general ),
I have seen gm crank's take a lot of punishment but you know,,,:)st I think fiat know's more than I , that's my .02 worth ,, :)hand ....Eric

Yes - I kinda knew it , didn't want to believe it ( china cranks ) So i gues the only right thing to do is save up and buy a good crank ..

Oh btw Mine has burped before and if I had lesser wrist pin's I would have had problem's , ( it flexed the pin but didn't break , took out the bushing thou ) ,,,I run the Feria heavy duty ( well worth their price ) ,, :)hand...Eric

I know it's probably too late, but alum. rods help soften the blow to the crank on blown alky.
Sent you a PM. I've got a good deal on Scat stuff as well.

Waddya guys talking about, Chevy cranks are the BOMB:



Seriously, anything that actually came from Cheverolet has no business in a blown alcohol engine....

callies compstar would be my obvious choice if i were building that, ya know they're right and they're cheap, will handle some power too! better quality than scat or eagle, and barely a 100bucks more:)bulb
