Which Crankshaft Is Best for Me?
Which Crankshaft Is Best for Me? Whats up all, I just needed some options to run this F1R blower.
I see a bunch of different options on crankshafts, so I needed to know what everyone recommends.. I had another post but wasn't to specific so I started a new one..
I'm building a 427 with an F1R on it, I have the aster bracket to go along with it..
my main question is if a Manley crank will hold? I see some people having issues with the dragonslayer crank so I feel kinda eh about using that one..
Also, do I need a long snout crank?
Other than manley, whats another good option to atleast be safe at 1k hp?
PLEASE TELL ME I DONT NEED A BILLET CRANK
thanks

WEGNER Pulley Kit HI Manny, WHAT is a F1R Supercharger ?
The S/C Pulley kit designed by Casey Wegner places the "blower" belt FIRST, the closest to the Timing Cover.
You may want to look at some of the GMPP crankshaft options.
I could supply a Crower Crankshaft ?

Callie's Magnum & XL are still 100% Forged & Finished in the USA I was
Told when I bought mine 2 years ago, as opposed
To forged offshore and finished here (compstar & dragonslayer).
I would/did chose a totally USA made Crank, Forged rather then Billet.
Above 1000 Crank HP Quality becomes evermore apparent.

Manny, it honestly depends on what your doing with the car. If it's in full boost all day long, vs. an occasional hit on the highway...there's an obvious difference in needs and wants. It's your money, and believe me, guys here will spend it for you.
If I were you, and it's not a full on race car, I'd run my Manley.
If it's a full on race car, I'd go billet.

Thanks for the response guys.
Car will see more street time than anything. I'm very hard on it when I do drive it. I'm always under the impression that over building it will be best to avoid any issues. I was thinking of a billet crank but they are a bit pricy.
I will also see some track time here and there but nothing crazy. Will pretty much be a weekend warrior.
My goals are to have a streetable track car but also be able to beat it without worry of breaking the crank.

Not 100% sure if it's true but on Yellowbullet several people stated the the magnum is the same forging as the Dragonslayer but has more finish machine work done on it.
"Compstar Performance Crankshafts are designed by our engineers, and forged on proprietary dies, made to our specifications. They are rough machined from certified 4340 forgings to our tolerances, then finish machined in our facility."
What issues are you hearing about the Dragonslayer?
I would call Callies and see what they recommend, The fact that you're running a supercharger off of the snout will be a consideration. When I called them about my 408 roots bower build they recommended a Magnum if on a budget and assured me that it would be up to the task.

But did you read the whole post?...this line in particular..what Tony neglects to post is the crank has done many years service. On last tear down it was shown to him the crank was being flexed by his drive set up and the tension on the belt.

I think what it meant was that the Dart blocks are the only ones the crank will drop right into since they're already machined for it.

As mentioned in the ad, that's actually not entirely accurate information, they will work with any block if you machine the #3 main saddle in the block. I know of a couple LSX blocks is running them in big power adder applications.

I don't remember much needs to be milled out, but it's not much. If your machinist puts it up on the end mill, it might take 30 minutes if he's done it before. If he has to mill, test fit, mill more, etc then it would take longer.
